Apart from better performance when accessing thread local variables,
we'll get rid of things that depend on initialization/cleanup of
pthread_key_t variables.
Where appropriate, use compiler-dependent pre-C++11 thread-local
equivalents, where it makes sense, to avoid initialization check overhead
that non-static thread_local can suffer from.
MDEV-32188 make TIMESTAMP use whole 32-bit unsigned range
This is done by changing my_time_t from long to unsigned long.
The effect of this is that on windows compling old clients may
get warnings of if they compare my_time_t with as signed variable.
Other things
- Removed my_time_t from include/*.pp files as it is different on windows
and linux.
- Changed do_abi_check.cmake to first print abi_check and then the
conflicting file (this makes it easier to find the cause of the error).
Add doxygen markup so comments get picked up. Also fix minor typos and
expand documentation where relevant.

MDEV-33308 CHECK TABLE is modifying .frm file even if --read-only
As noted in commit d0ef1aaf61,
MySQL as well as older versions of MariaDB server would during
ALTER TABLE ... IMPORT TABLESPACE write bogus values to the
PAGE_MAX_TRX_ID field to pages of the clustered index, instead of
letting that field remain 0.
In commit 8777458a6e this field
was repurposed for PAGE_ROOT_AUTO_INC in the clustered index root page.
To avoid trouble when upgrading from MySQL or older versions of MariaDB,
we will try to detect and correct bogus values of PAGE_ROOT_AUTO_INC
when opening a table for the first time from the SQL layer.
btr_read_autoinc_with_fallback(): Add the parameters to mysql_version,max
to indicate the TABLE_SHARE::mysql_version of the .frm file and the
maximum value allowed for the type of the AUTO_INCREMENT column.
In case the table was originally created in MySQL or an older version of
MariaDB, read also the maximum value of the AUTO_INCREMENT column from
the table and reset the PAGE_ROOT_AUTO_INC if it is above the limit.
dict_table_t::get_index(const dict_col_t &) const: Find an index that
starts with the specified column.
ha_innobase::check_for_upgrade(): Return HA_ADMIN_FAILED if InnoDB
needs upgrading but is in read-only mode. In this way, the call to
update_frm_version() will be skipped.
row_import_autoinc(): Adjust the AUTO_INCREMENT column at the end of
ALTER TABLE...IMPORT TABLESPACE. This refinement was suggested by
Debarun Banerjee.
The changes outside InnoDB were developed by Michael 'Monty' Widenius:
Added print_check_msg() service for easy reporting of check/repair messages
in ENGINE=Aria and ENGINE=InnoDB.
Fixed that CHECK TABLE do not update the .frm file under --read-only.
Added 'handler_flags' to HA_CHECK_OPT as a way for storage engines to
store state from handler::check_for_upgrade().

it's for client auth plugins only, server auth plugin should never
return it, because they cannot send a correct OK packet.
(OK packet is quite complex and carries a lot of information that
only the server knows)
Since 0930eb86cb, system table creation
needed for spider init is delayed to the signal_ddl_recovery_done
callback. Since it is part of the init, failure should result in
spider deinit.
We also remove the call to spider_init_system_tables() from
spider_db_init(), as it was removed in the commit mentioned above and
accidentally restored in a merge.
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.

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).
- Adding automatic conversion operator from LEX_STRING to LEX_CSTRING
Now a LEX_STRING can be passed directly to any function expecting
a LEX_CSTRING parameter passed by value or by reference.
- Removing a number of duplicate methods accepting LEX_STRING.
Now the code used the LEX_CSTRING version.
