Another batch of changes that should make the SST process
more reliable in all scenarios:
1) Added hostname or CN verification when stunnel is used
with certificate chain verification (verifyChain = yes);
2) Added check for the absence of the stunnel utility for
mtr tests;
3) Deletion of working files before and after SST is done
more accurately;
4) rsync on joiner can be run even if the path to its
configuration file contains spaces;
5) More accurate directory creation (for data files and
for logs);
6) IST with mysqldump no longer turns off statement logging;
7) Reset password for mysqldump when password is empty but
username is specified;
8) More reliable quoting when generating statements in
wsrep_sst_mysqldump;
9) Added explicit generation of 2048-bit Diffie-Hellman
parameters for sockat < 1.7.3, by analogy with xtrabackup;
10) Compression parameters for qpress are read from all
suitable server groups in configuration file, as well as
from the [sst] and [xtrabackup] groups;
11) Added a test that checks compression using qpress;
12) Checking for optional utilities is modified to work even
if they implemented as built-in shell commands (unlikely
on real systems, but more reliable).

1) This commit implements reading all sections from configuration
files while looking for the current value of any server variable,
which were previously only read from the [mysqld.suffix] group and
from [mysqld], but not from other groups such as [mariadb.suffix],
[mariadb] or, for example, [server].
2) This commit also fixes misrecognition of some parameters when
parsing a command line containing a special marker for the end
of the list of options ("--") or when short option names (such
as "-s", "-a" and "-h arg") chained together (like a "-sah arg").
Such parameters can be passed to the SST script in the list of
arguments after "--mysqld-args" if the server is started with a
complex set of options - this was revealed during manual testing
of changes to read configuration files.
3) The server-side preparation code for the "--mysqld-args"
option list has also been simplified to make it easier to change
in the future (if needed), and has been improved to properly
handle the special backquote ("`") character in the argument
values.

This commit contains a large set of further bug fixes and
improvements to SST scripts for Galera, continuing the work
that was started in MDEV-24962 to make SST scripts work smoothly
in different network configurations (especially using ipv6) and
with different environment settings:
1) The ipv6 addresses were incorrectly handled in the SST script
for rsync (incorrect address substitution for establishing a
connection, incorrect address substitution for bind, and so on);
2) Checking the locality of the ip-address in SST scripts did not
support ipv6 addresses (such as "[::1]"), which were falsely
identified as non-local ip, which further did not allow running
two SSTs on different local addresses on the same machine.
On the other hand, this bug masked some other errors (related
to handling ipv6 addresses);
3) The code for checking the locality of the ip address was different
in the SST scripts for rsync and for mysqldump, with individual
flaws. This code is now made common and moved to wsrep_sst_common;
4) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
did not process ipv6 addresses correctly in all cases (not for all
branches);
5) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
for some code branches could give a false positive result due to
the textual match of prefixes in the port number and/or PID of
the process;
6) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) was supported through different utilities in SST scripts
for mariabackup and for rsync, and with various minor flaws in
the code. Now the code is still different in these scripts, but
it supports a common set of utilities (lsof, ss, sockstat) and
is synchronized across patterns that used to check the output
of these utilities;
7) In SST via mariabackup, the signal about readiness to receive data
is sometimes sent too early - immediately after listen(), and not
after accept() (which are called by socat or netcat utility).
8) Checking availability of the some options of some utilities was
done using the grep pattern, which easily gives false positives;
9) Common name (CN) for local addresses, if not explicitly specified,
is now always replaced to "localhost" to avoid the need to generate
many separate certificates for local addresses of one machine and
not to depend on which the local address is currently used in test
(ipv4 or ipv6, etc.);
10) In tests galera_sst_mariabackup_encrypt_with_key_server and
galera_sst_rsync_encrypt_with_key_server the correct certificate
is selected to avoid commonname (CN) mismatch problems;
11) Further refactoring to protect against spaces in file names.
12) Further general refactoring to eliminate bash-specific constructs
or to improve code readability;
13) The code for setting options for the nc (netcat) utility was
different in different scripts for SST - now it is made identical.
14) Fixed long-time broken encryption via xbcrypt in combination with
mariabackup and added support for key-based encryption via openssl
utility, which is now enabled by default for encrypt=1 mode (this
default mode can be changed using a new configuration file option
"encypt-format=openssl|xbcrypt", which can be placed in the [mysqld],
[sst] or in the [xtrabackup] section) - this change will allow us
to use and to test the encypt=1 encryption without installing
non-standard third-party utilities.

After switching to the new mariabackup interface (instead of
the outdated innobackupex interface, which is supported for
compatibility), we need to explicitly pass a path to the datadir
directory as a parameter, since in the new interface the value
of this option is not automatically set in such a way that it
always matches the SST/IST logic. This commit adds passing this
option as an explicit parameter to mariabackup. This commit also
removed unnecessary options that are not used and not supported
by mariabackup.
Also, numerous flaws in the common wsrep_sst_common script have
been fixed:
1) There are many bash-specific constructs in the script that
may not be supported by other interpreters, which can lead
to the most unexpected errors during SST, because failures
in the interpretation of bash-specific constructs lead to
incorrect parsing of arguments;
2) There is parse_cnf() function which is often called by other
scripts for the "mysqld" or "--mysqld" group, but it does not
take into account the default group suffix, which leads to
reading values only from the default group, which then leads
to errors due to reading the default values instead of the
values for a specific group;
3) Some options such as --user, --innodb-data-home-dir or --datadir
are not removed from the --mysqld-args list, although they are
processed inside scripts (and passing of these options funther
may cause problems for mariabackup);
4) If an argument that the script understands is present in
the --mysqld-args list twice, then this causes SST to fail,
instead of reading the most recent value;
5) The "--host" parameter is technically still supported among
the arguments of the SST scripts, but in reality scripts do not
work with it as expected, especially if it has an IPv6 address;
6) If the port number is absent in the --address parameter value,
but the port number is explicitly passed through the --port
argument, then the scripts for mariabackup and xtrabackup-v2
fail;
7) If a new address interface is used (with the --address parameter),
then automatic default port substitution is not performed, although
it is supported for the legacy --host/--port interface.
8) If there are spaces in the parameter values after --mysqld_args,
then their further transfer does not occur correctly, which
causes mariabackup to fail during SST - the space splits
the argument in such a way that it breaks the parsing of the
following parameters;
9) If most of the parameters that are names or paths to the files
or directories contain spaces, then SST scripts fail in an
unpredictable way due to incorrect variable substitutions;
10) If the --log-bin option is passed among the arguments of myqlds
(--mysqld-args) without a parameter, and the --binlog option
is not specified, then the script cannot substitute the default
name for binlog and cannot construct binlog name using the
--log-basename argument (which is against server specifications);
11) Tail slashes are not removed from the directory names, which,
upon further substitution, leads to the appearance of a double
slash in the file paths;
12) The explicit --binlog parameter (which is now always transmitted
from the server side) and the "hidden" --log-bin parameter in the
list of arguments after --mysqld-args are perceived as two different
parameters in different parts of the scripts, and if they are do not
match for some reason, this will lead to failures during SST;
Also, all new changes from the 10.6 branch have been migrated here,
including the latest pull requests for authentication (only the part
that concerns SST scripts).
It also fixes dozens of other bugs in all SST scripts.

Removed numerous extra blank lines and spaces that interfere with
reading and understanding program code, making it more difficult to
find errors in scripts. I also removed all extra trailing spaces at
the ends of lines, which lead to marking extra lines as changes
(in subsequent changes). The amount of indentation in some parts
of the code has also been normalized.

SST scripts for Galera should use the new mariabackup interface
instead of the innobackupex interface, which is currently only
supported for compatibility reasons.
This commit converts the SST script for mariabackup to use the
new interface. It does not need separate tests, as any problems
will be seen as failures when running multiple tests for the
mariabackup-based SST.

This script is unused and unmaintained.
The logic is implemented in scripts/mysql_system_tables_fix.sql that forms part of mysql_upgrade
Its components:
alter table mysql.user drop column `password_last_changed`, drop column `password_lifetime`, drop column `account_locked`;
has a friendlier migration path coming MDEV-24122
alter table mysql.user change column `authentication_string` `auth_string` text COLLATE utf8_bin NOT NULL;
Already part of scripts/mysql_system_tables_fix.sql
alter table mysql.user add column `Password` char(41) CHARACTER SET latin1 COLLATE latin1_bin NOT NULL DEFAULT '' after `user`, add column `is_role` enum('N','Y') CHARACTER SET utf8 NOT NULL DEFAULT 'N' after `auth_string`;
alter table mysql.user add column `default_role` char(80) COLLATE utf8_bin NOT NULL DEFAULT '', add column `max_statement_time` decimal(12,6) NOT NULL DEFAULT '0.000000';
corrected in MDEV-23201 to be in the right order.
update mysql.user set `password`=`auth_string`, plugin='' where plugin="mysql_native_password";
Is handled in server in the function acl_load.

Mariabackup SST fails if "--log-bin" option is added with no value
to command line parameters at server startup. This is because the SST
scripts do not correctly interpret the "--- log-bin" option without a
value. This patch adds correct handling of the "--log-bin" parameter
without value to the general part of the parameter parsing (for SST
scripts) and fixes the problem. Also added a test that checks the
correct operation of the server after the fix.

Adding any unknown option to the "[mysqld_safe]" section makes
mysqld impossible to start with mysqld_multi. For example, after
adding the unknown option "numa_interleave" to the "[mysqld_safe]"
section, mysqld_multi exits with the following diagnostics:
[ERROR] /usr/local/mysql/bin/mysqld: unknown option '--numa_interleave'
To get rid of this behavior, this patch adds the passing of the default
group suffix from mysqld_multi to the mysqld_safe side.

In galera_3nodes.galera_safe_to_bootstrap node restart can happen too soon, when earlier SST joiner process is still active in the node.
Similar issue may hurt other mtr tests as well.
This is second variant of fix for this issue. Here we only change rsync SST script to wait a little bit if lingering SST rsync is observed to be in execution.
We assume that the previous mysqld and SST processes have been already signaled to abort during earlier stataup attempt.
If other SST methods (than rsync) suffer from similar overlapping SST execution, they should be sorted out separately within each SST method handler scripts.

To fix this, it is necessary to add an option to exclude the
database with the name "lost+found" from processing (the database
name will be checked by the check_if_skip_database_by_path() or
by the check_if_skip_database() function, and as a result
"lost+found" will be skipped).
In addition, it is necessary to slightly modify the verification
logic in the check_if_skip_database() function.
Also added a new test galera_sst_mariabackup_lost_found.test

This patch fixes several flaws in the SST scripts that cause
failures while running tests that use version 6 IP addresses
for cluster nodes.
First, if the netcat utility is used for streaming (but not socat),
then in accordance with its command line syntax, we need to remove
the square brackets around the IPv6 address. However, for socat,
the address must contain square brackets, as before.
Secondly, if an IPv6 address is used, then from the joiner side for
a number of systems (such as Debian) we need to explicitly specify
the "-6" option, otherwise a listening socket with an IPv6 address
may not be created.
This patch also contains code improvements in the wsrep_sst_common.
Changed the code that pars the connection address - fixed the
shortcomings that sometimes led to incorrect parsing of parameters
when using shells other than the latest versions of bash.
Also, this patch removes the duplicate code that is intended
for parsing the connection address and which was located in the
wsrep_sst_mariabackup file, since all the necessary actions have
already been done in wsrep_sst_common and there they are done in
such a way that any shell is supported, not just bash.
The fix does not require separate tests, since all the
necessary tests are already present in the galera_3nodes suite.
On the contrary, after this fix, tests using IPv6 addresses can
be removed from the disabled list (this will be done in a separate
commit related to MDEV-23659).

Leave debian/additions/mysqlreport as #!/usr/bin/perl
Acknowledge that `env perl` is a hack, a complete fix
needs to consider which path perl is at and insert into
these scripts.
The usefulness of these scripts is questionable.

Adding any unknown option to the "[mysqld_safe]" section makes
mysqld impossible to start with mysqld_multi. For example, after
adding the unknown option "numa_interleave" to the "[mysqld_safe]"
section, mysqld_multi exits with the following diagnostics:
[ERROR] /usr/local/mysql/bin/mysqld: unknown option '--numa_interleave'
To get rid of this behavior, this patch by default adds the "--loose-"
prefix to all unknown (for mysqld_safe) options. This behavior can be
enabled explicitly with the --ignore-unknown option and disabled with
the --no-ignore-unknown option.

The problem is caused by the fact that adding the
--defaults-group-suffix option to fix MDEV-18863 causes
mysqld to read all options from the appropriate sections
of the config file, including options specific to mysqld_multi.
Reading unknown options (which are not supported by mysqld)
causes mysqld to terminate with an error.
However, the MDEV-18863 problem has been completely fixed
by passing options on the command line, and now there is no
need to specify the --defaults-group-suffix option (we just
need to give priority to options passed through the command
line, so as not to break MDEV-18863).

Removed duplicate.
Also move the --no-defaults option close to the other "default*"
options.

On FreeBSD, perl isn't in /usr/bin, its in /usr/local/bin or
elsewhere in the path.
Like storage/{maria/unittest/,}ma_test_* , we use /usr/bin/env to
find perl and run it.

Fix for Galera rsync SST with the specific conditions listed in MDEV-21709

The problem is caused by the operation of netcat streamer and does
not appear on systems where socat is installed. We need to add the
"-N" option for netcat to call shutdown() on the socket when receiving
EOF from STDIN.

Also add a check for tmp file being empty and bail out with a clear
error message in such a case, as mysqld_safe prevents normal stderr
from being displayed anywhere and would fail silently on this.

The log file is opened as root since commit bb7a70c, so there is no need
to chown it.

Setting "streamfmt=mbstream" in the "[sst]" section causes SST to fail
because the format automatically switches to 'tar' by default (insead
of mbstream).
To fix this, we need to add mbstream to the list of valid values for
the format, making it synonymous with xbstream. This must be done both
in the SST script and when parsing the options of the corresponding
utilities.
