This commit fixes GTID inconsistency which was injected by mariabackup SST.
Donor node now writes new info file: donor_galera_info, which is streamed
along the mariabackup donation to the joiner node. The donor_galera_info
file contains both GTID and gtid domain_id, and joiner will use these to
initialize the GTID state.
Commit has new mtr test case: galera_3nodes.galera_gtid_consistency, which
exercises potentially harmful mariabackup SST scenarios. The test has also
scenario with IST joining.

InnoDB could return off-by-1 estimates for the involved tables.
This would cause off-by-many difference in join output cardinality
for the top-level SELECT, and so different query plan for the subquery.
The fix: Introduce mysql-test/include/innodb_stable_estimates.{inc,opt}
which disables InnoDB's background statistics collection, and use it.
Fix some random test failures following MDEV-32168 push.
Don't blindly set $rpl_only_running_threads in many places. Instead explicit
stop only the IO or SQL thread, as appropriate. Setting it interfered with
rpl_end.inc in some cases. Rather than clearing it afterwards, better to
not set it at all when it is not needed, removing ambiguity in the test
about the state of the replication threads.
Don't fail the test if include/stop_slave_io.inc finds an error in the IO
thread after stop. Such errors can be simply because slave stop happened in
the middle of the IO thread's initial communication with the master.

Test rpl.show_status_stop_slave_race-7126 now fails sporadically
because it is expected to sometimes (but not always) leave an error
condition after slave stop. Fix by explicitly allowing the error
condition in this case.

- Regression introduced in 957cb7b7ba
- Patch 4abb8216a0 change `mysql.user` to `mysql.global_priv` for
`add_anonymous.inc`, update `delete_anonymous.inc`.
- Added test case with `--skip-name-resolve`
- Add test case with anonymous user
- Disable this test for windows, assignes current user to anonymous
user.

Also fixes: MDEV-30050 Inconsistent results of DISTINCT with NOPAD
Problem:
Key segments for CHAR columns where compared using strnncollsp()
for engines MyISAM and Aria.
This did not work correct in case if the engine applyied trailing
space compression.
Fix:
Replacing ha_compare_text() calls to new functions:
- ha_compare_char_varying()
- ha_compare_char_fixed()
- ha_compare_word()
- ha_compare_word_prefix()
- ha_compare_word_or_prefix()
The code branch corresponding to comparison of CHAR column keys
(HA_KEYTYPE_TEXT segment type) now uses ha_compare_char_fixed()
which calls strnncollsp_nchars().
This patch does not change the behavior for the rest of the code:
- comparison of VARCHAR/TEXT column keys
(HA_KEYTYPE_VARTEXT1, HA_KEYTYPE_VARTEXT2 segments types)
- comparison in the fulltext code
The MDEV-29693 conflict resolution is from Monty, as well as is
a bug fix where ANALYZE TABLE wrongly built histograms for
single-column PRIMARY KEY.
Also includes a fix for safe_malloc error reporting.
Other things:
- Copied main.log_slow from 10.4 to avoid mtr issue
Disabled test:
- spider/bugfix.mdev_27239 because we started to get
+Error 1429 Unable to connect to foreign data source: localhost
-Error 1158 Got an error reading communication packets
- main.delayed
- Bug#54332 Deadlock with two connections doing LOCK TABLE+INSERT DELAYED
This part is disabled for now as it fails randomly with different
warnings/errors (no corruption).
The bug was in the test case.
The problem was that maria_empty_logs.inc deleted aria log files before
the server was properly shutdown.
Fixed by waiting for pid file to disappear before starting to delete log
files.
Other things:
- Fixed that translog_purge_at_flush() will not stop deleting files even
if one file could not be deleted.
- Remove extra connections in the form of `server_number_1` for the same server
during initialization of servers in the `rpl_init.inc` file.
- Remove disconnecting and reconnecting to the same connections,
since they are not used by the test.
- Update comments about the above.

- Fix the calling of the assertion condition when `rpl_check_server_ids` parameter is used.
- Fix comments regarding the default usage and configuration files
extension in this case.

* version_compile_os can be "linux-systemd", not equal to "Linux"
* main.no-threads forces no-threads scheduler, a check whether it
has one_thread_per_connection is guaranteed to fail.
Currently include/have_innodb_4k.inc etc. files only check that the
server is running with the corresponding page size. I think it would
be more convenient if they actually enforced the setting.
The problem is that s390x is not using the default bzip library we use
on other platforms, which causes compressed string lengths to be differnt
than what mtr tests expects.
Fixed by:
- Added have_normal_bzip.inc, which checks if compress() returns the
expected length.
- Adjust the results to match the expected one
- main.func_compress.test & archive.archive
- Don't print lengths that depends on compression library
- mysqlbinlog compress tests & connect.zip
- Don't print DATA_LENGTH for SET column_compression_zlib_level=1
- main.column_compression
