Gtid_log_list_event
If a slave received a fake GLLE event after a GTID event
it would terminate the group. This adds a test for the
previous commit which fixed this issue (939672a).

GTID_LIST_EVENT or INCIDENT_EVENT.
It's legal to have either of the two inside a group. E.g
Gtid_event, Gtid_log_list_event, Query_1, ... Xid_log_event
is permitted.
However, the slave IO thread treated both
as the terminal even when the group represents a DDL query.
That causes a premature Gtid state update so the slave IO would think
the whole group has been collected while in fact Query_1 etc are yet to process.
Fixed with correcting a condition to compute the terminal event
of the group.
Tested with rpl_mysqlbinlog_slave_consistency (of 10.9) and
rpl_gtid_errorlog.test.

This commit sends a flag indicating the presence of the "--bypass"
option from the donor node to the joiner nodes during rsync IST,
because without such a flag it is impossible to distinguish IST
from the SST on the joiner nodes (in IST/SST scripts, because the
"--bypass" option is still not passed to scripts from server code).
Specifically, this fixes an issue with binary logs disappearing
after IST (via rsync). There are also changes to diagnostic messages
here that will make it easier to diagnose script-related problems
in the future when debugging and when checking the logs. This commit
also adds more robust signal handlers - to handle exceptions during
script execution. These handlers won't mask some crashes and it
also unifies exit codes between different scripts. These changes
have already been helpful to debugging "bypass" flag handling.

This commit fixes an issue with IST handling in
version 10.9 which is a regression after MDEV-26971
and related to trying to get a non-existent "total"
tag on the IST branch (this tag is only defined in
SST mode).

The counter srv_stats.key_rotation_list_length is never updated, and
therefore Innodb_encryption_key_rotation_list_length will always be 0.
The view INFORMATION_SCHEMA.INNODB_TABLESPACES_ENCRYPTION comes close
to reporting this information.

num_non_index_pages_written
The counters were added in commit 5e55d1ced52c52fb2f0508e1346059901a85960f
and any code to update them was
inadvertently removed in commit 2e814d4702d71a04388386a9f591d14a35980bfe
when applying InnoDB changes from MySQL 5.7.
Let us remove these counters that never reported anything useful. If such
statistics are really needed in a special case, they can be obtained by
instrumenting the code by some means, such as eBPF or a source code patch.

- In best_extension_by_limited_search(), do not check for
"(remaining_tables & real_table_bit)", it is guaranteed to be true.
Make it an assert.
- In (!idx || check_interleaving_with_nj())", remove the !idx part.
This check made sense only in the original version of this function.

Function wsrep_read_only_option was already removed in commit
d54bc3c0d1 because it could cause race condition on variable
opt_readonly so that value OFF can become permanent.
Removed function again and added test case. Note that writes

slave setup
This patch fixes a problem that arises when a Galera node acts as a
replica for native replication. When parallel applying is enabled, it
is possible to end up with attempts to write binlog events with gtids
out of order. This happens because when multiple events are delivered
from the native replication stream and applied in concurrently, it is
for them to be replicated to the Galera cluster in an order which is
different from the original order in which they were committed in the
aync replication master.
To correct this behavior we now wait_for_prior_commit() before
replicating changes though galera. As a consequence, parallel appliers
may apply events in parallel until the galera replication step, which
is now serialized.

Arythmetic can overrun the uint type when possible group_concat_max_len

MDEV-21810 MBR: Unexpected "Unsafe statement" warning for unsafe IODKU
MDEV-17614 fixes to replication unsafety for INSERT ON DUP KEY UPDATE
on two or more unique key table left a flaw. The fixes checked the
safety condition per each inserted record with the idea to catch a user-created
value to an autoincrement column and when that succeeds the autoincrement column
would become the source of unsafety too.
It was not expected that after a duplicate error the next record's
write_set may become different and the unsafe decision for that
specific record will be computed to screw the Query's binlogging
state and when @@binlog_format is MIXED nothing gets bin-logged.
This case has been already fixed in 10.5.2 by 91ab42a823 that
relocated/optimized THD::decide_logging_format_low() out of the record insert
loop. The safety decision is computed once and at the right time.
Pertinent parts of the commit are cherry-picked.
Also a spurious warning about unsafety is removed when MIXED
@@binlog_format; original MDEV-17614 test result corrected.
The original test of MDEV-17614 is extended and made more readable.

In SELECT_LEX::update_used_tables(),
do not run the loop setting tl->table->maybe_null
when tl is an eliminated table
(Rationale: First, with current table elimination, tl already
has maybe_null=1. Second, one should not care what flags
eliminated tables had)

(This is the assert that was added in fix for MDEV-26047)
Table elimination may remove an ON expression from an outer join.
However SELECT_LEX::update_used_tables() will still call
item->walk(&Item::eval_not_null_tables)
for eliminated expressions. If the subquery is constant and cheap
Item_cond_and will attempt to evaluate it, which will trigger an
assert.
The fix is not to call update_used_tables() or eval_not_null_tables()
for ON expressions that were eliminated.

Window Functions code tries to minimize the number of times it
needs to sort the select's resultset by finding "compatible"
OVER (PARTITION BY ... ORDER BY ...) clauses.
This employs compare_order_elements(). That function assumed that
the order expressions are Item_field-derived objects (that refer
to a temp.table). But this is not always the case: one can
construct queries order expressions are arbitrary item expressions.
Add handling for such expressions: sort them according to the window
specification they appeared in.
This means we cannot detect that two compatible PARTITION BY clauses
that use expressions can share the sorting step.
But at least we won't crash.

Problem:
==============
By testing `pgrep` with `--ns` option,
introduced with MDEV-21331, commit fb7c1b9415c9a8b0dc2e86ae44f0e7a2634e5d7e,
I noted that:
a) `--ns` cannot use more than single PID.
b) `--ns` is returning the processes of the namespace to which supplied PID belongs to.
So by that sense command `pgrep -x --ns $$ mysqld` will always return an error and skip
checking of the existing PID of the server.
Solution:
==============
Suggested solution is to add `--nslist pid`, since `--ns` needs to know in which namespace type it should look for.
See `pgrep --help` for different namespace types.
Note also that this works *only* if script is run as a `root` (we have that case here).
Current PR is a part of:
1. MDEV-21331: sync preinst and postrm script
2. MDEV-15718: check for exact mysqld process
This commit:
a) fixes fb7c1b9415c9a8b0dc2e86ae44f0e7a2634e5d7e
b) Closes PR #2068 (obsolete)
c) Closes PR #2069 (obsolete)

Move </database> in xml mode until after the transaction_registry.
General_log and slow_log tables where moved to be first to be dumped so
that the disabling of the general/slow queries is minimal.

Previously the correct SQL mode for a stored routine or
package was only set before doing the CREATE part, this
worked out for PROCEDUREs and FUNCTIONs, but with ORACLE
mode specific PACKAGEs the DROP also only works in ORACLE
mode.
Moving the setting of the sql_mode a few lines up to happen
right before the DROP statement is writen fixes this.
