- Patch 95bb3cb8 used `my_which` function in `10.2`
- Based on patch `355ee687` from 10.3+ `command -v` is used instead of
`my_which` so we are changing in this patch also
- `ldconfig` is usually found in `/sbin` so make sure it is added in
`$PATH` variable

Bugs fixed:
- prepare_for_repair() didn't close all open files if table opened failed
  because of out-of-memory
- If dd_recreate_table() failed, the data file was not properly restored
  from it's temporary name
- Aria repair initializing code didn't properly clear all used structs
  before calling error, which caused crashed in memory-free calls.
- maria_delete_table() didn't register if table open failed. This could
  calls my_error() to be called without returning 1 to the caller, which
  cased failures in my_ok()

Note when merging to 10.5:
- Remove the #if MYSQL_VERSION from sql_admin.cc

C++11 is allowed only starting with MariaDB Server 10.4.

This follows up commit
commit 94a520dd and
commit 7c5519c1.

After these changes, the default test suites on a
cmake -DWITH_UBSAN=ON build no longer fail due to passing
null pointers as parameters that are declared to never be null,
but plenty of other runtime errors remain.

This was missed in commit d6ea03fa.

Add --system={all, users, plugins, udfs, servers, stats, timezones}

This will dump system information from the server in
a logical form like:
* CREATE USER
* GRANT
* SET DEFAULT ROLE
* CREATE ROLE
* CREATE SERVER
* INSTALL PLUGIN
* CREATE FUNCTION

"stats" is the innodb statistics tables or EITS and
these are dumped as INSERT/REPLACE INTO statements
without recreating the table.

"timezones" is the collection of timezone tables
which are important to transfer to generate identical
results on restoration.

Two other options have an effect on the SQL generated by
--system=all. These are mutually exclusive of each other.
* --replace
* --insert-ignore

--replace will include "OR REPLACE" into the logical form
like:
* CREATE OR REPLACE USER ...
* DROP ROLE IF EXISTS (MySQL-8.0+)
* CREATE OR REPLACE ROLE ...
* UNINSTALL PLUGIN IF EXISTS (10.4+) ... (before INSTALL PLUGIN)
* DROP FUNCTION IF EXISTS (MySQL-5.7+)
* CREATE OR REPLACE [AGGREGATE] FUNCTION
* CREATE OR REPLACE SERVER

--insert-ignore uses the construct " IF NOT EXISTS" where
supported in the logical syntax.

'CREATE OR REPLACE USER' includes protection against
being run as the same user that is importing the mysqldump.

Includes experimental support for dumping mysql-5.7/8.0
system tables and exporting logical SQL compatible with MySQL.

Updates mysqldump man page, including this information and
(removing obsolute bug reference)

This is a partial backport of

 MDEV-24033: SIGSEGV in __memcmp_avx2_movbe from queue_insert | SIGSEGV in __memcmp_avx2_movbe from native_compare

The issue here was the system variable max_sort_length was being applied
to decimals and it was truncating the value for decimals to the number
of bytes set by max_sort_length.
This was leading to a buffer overflow as the values were written
to the buffer without truncation and then we moved the offset to
the number of bytes(set by max_sort_length), that are needed for comparison.

The fix is to not apply max_sort_length for fixed size types like INT,
DECIMALS and only apply max_sort_length for CHAR, VARCHARS, TEXT and
BLOBS.

cmake has caught up and since version 3.18 it started supporting
CPACK_RPM_POST_TRANS_SCRIPT_FILE, something we've supported for
two years and cmake 2.8.11. Both implementation add %posttrans tag
and rpmbuild gets confused.

Disable our implementation for cmake 3.18+

Test itself is not deterministic.

Use 9 byte (min length packet)

The crash happens because a double free in the case CREATE TABLE fails
because there is a conflicting tables on disk.

Fixed by ensuring that the double free can't happen.

On my system, OpenSuse, I got a compilation error that some arguments
to getgrouplist() where not initialized

The problem was that opt_sum_query() was, as part of MIN/MAX optimization,
doing read operations on constant tables that where already closed

Fixed by ensuring we don't try to read from tables that are closed.

and restore the test modified in the same commit
(the non-replication related deadlock will be reported separately)

Implement a different fix for
"MDEV-19232: Floating point precision / value comparison problem"

Instead of truncating decimal values after every division,
truncate them for comparison purposes.

This reverts commit 62d73df6 but keeps the test.

followup for 3e807d25 and eae10a87

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

An assertion inadvertently contained an assignment and an implicit
comparison to zero. The intention was to test equality.
