- mysqlnd from PHP < 7.3
- mysql-connector-python any version
- mysql-connector-java any version
Relaxed check about garbage at the end of the packet in case of no parameters.
Added check for array binding.
Fixed test according to the new paradigm (allow junk at the end of the packet)

In case of direct execution(stmtid=-1, mariadb_stmt_execute_direct in C
API) application is in control of how many parameters client sends to
the server. In case this number is not equal to actual query parameters
number, the server may start to interprete packet data incorrectly, e.g.
starting from the size of null bitmap. And that could cause it to crash
at some point. The commit introduces some additional COM_STMT_EXECUTE
packet sanity checks:
- checking that "types sent" byte is set, and the value is equal to 1.
if it's not direct execution, then that value is 0 or 1.
- checking that parameter type value is a valid type, and parameter
flags value is 0 or only "unsigned" bit is set
- added more checks that read does not go beyond the end of the packet

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.

For some reason, adding -fsanitize=undefined (cmake -DWITH_UBSAN=ON)
to the compilation flags will cause even more warnings to be emitted.
The warning was a bogus one:
tests/mysql_client_test.c:8632:22: error: '%d' directive writing between
1 and 11 bytes into a region of size 9 [-Werror=format-overflow=]
8632 | sprintf(field, "c%d int", i);
| ^~
tests/mysql_client_test.c:8632:20: note: directive argument
in the range [-2147483648, 999]
The warning does not take into account that the lower bound of the
variable actually is 0. But, we can help the compiler and use an
unsigned variable.

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.

When a prepared statement parameter '?' is used in a CTE that is used
multiple times, the following happens:
- The CTE definition is re-parsed multiple times.
- There are multiple Item_param objects referring to the same "?" in
the original query.
- Prepared_statement::param has a pointer to the first of them, the
others are "clones".
- When prepared statement parameter gets the value, it should be passed
over to clones with param->sync_clones() call.
This call is made in insert_params(), etc. It was not made in
insert_params_with_log().
This would cause Item_param to not have any value which would confuse
the query optimizer.
Added the missing call.

Type_handler_xxx::Item_const_eq() can handle only non-NULL values.
The code in Item_basic_value::eq() did not take this into account.
Adding a test to detect three different combinations:
- Both values are NULLs, return true.
- Only one value is NULL, return false.
- Both values are not NULL, call Type_handler::Item_const_eq()
to check equality.

post-merge fixes:
* .gitignore
* don't put the keyword COMPONENT into ${COMP} anymore
* don't alias mytop, but do alias mysql_client_test
* don't symlink manpages, use troff aliasing technique instead
(symlinked manpages break rpm and out-of-source bintar builds)
* move debian to use troff aliased manpages, fix typos in debian files,
put aliases in the correct packages, add more aliases to match
rpm/bintar packaging

- --skip-resolve can be be disabled in mysqld
- mysql_client_test now resets global variables it changes
- mtr couldn't handle [mysqldump] in config files (wrong regexp used)

The bug was that when using mysql_list_fields, then
table_list->schema_table_name was not filled in.
Fixed by using table_list->schema_table instead, which is always
filled in.

Timestamp_or_zero_datetime_native_null::Timestamp_or_zero_datetime_native_null upon mysqld_list_fields after crash recovery
The problem happened because Item_ident_for_show did not implement val_native().
Solution:
- Removing class Item_ident_for_show
- Implementing a new method Protocol::send_list_fields() instead,
which accepts a List<Field> instead of List<Item> as input.
Now no any Item creation is done during mysqld_list_fields().
Adding helper methods, to reuse the code easier:
- Moved a part of Protocol::send_result_set_metadata(),
responsible for sending an individual field metadata,
into a new method Protocol_text::store_field_metadata().
Reusing it in both send_list_fields() and send_result_set_metadata().
- Adding Protocol_text::store_field_metadata()
- Adding Protocol_text::store_field_metadata_for_list_fields()
Note, this patch also automatically fixed another bug:
MDEV-18685 mysql_list_fields() returns DEFAULT 0 instead of DEFAULT NULL for view columns
The reason for this bug was that Item_ident_for_show::val_xxx() and get_date()
did not check field->is_null() before calling field->val_xxx()/get_date().
Now the default value is correctly sent by Protocol_text::store(Field*).
