(that is MY_CHECK_C_COMPILER_FLAG, MY_CHECK_CXX_COMPILER_FLAG,
MY_CHECK_AND_SET_COMPILER_FLAG)

This is to have a clear "internal" name prefix and to avoid
mixing them with hand-named symbols

A preparatory task for:
  MDEV-4912 Add a plugin to field types (column types)

wsrep.cmake should be included before cpack_rpm.cmake as it defines
WITH_WSREP, required by cpack_rpm.cmake to conditionally include galera
helper tools in server package's requires list.

--with-plugin-name=xxxx
--with-plugins= now uses =AUTO instead of =1

1. define connect_EXPORTS, this causes the engine to use MariaDB
   versions for timestamp<->struct tm conversion instead of
   TZ-dependent libc versions.
2. remove check_access() that was removed once, but re-appeared
   during a complex merge.
3. disable a totally broken test
4. update test results
5. skip odbc_firebird test when no firebird DSN is available

Apply MySQL fix for bug#76727:
https://github.com/mysql/mysql-server/commit/69d4e72c

  Bug#20901025: SLAVE ASSERTION IN UNPACK_ROW WITH ROLLBACK TO
  SAVEPOINT IN ERROR HANDLER

feedback was bzero-ing thd->status_vars.memory_used,
but server was asserting the correct value of it

RENAME TABLE code tries to update EITS statistics. It hung, because
it used an index on (db_name,table_name) to find the table, and attempted
to update these values at the same time. The fix is do what SQL UPDATE
statement does when updating index that it's used for scanning:
- First, buffer the rowids of rows to be updated,
- then make the second pass to actually update the rows

Also fixed the call to rename_table_in_stat_tables() in sql_rename.cc
to pass the correct new database (before, it passed old db_name so cross-
database renames were not handled correctly).

Variant #2, with review feedback addressed.

rpl/rpl_mdev382     ; Wrong replace in show_binlog_events2.inc
binlog/database     ; Different error on Solaris if file exists
mroonga/repair_table_no_index_file ; Different system error on Solaris
partition_not_blackhole ; Different error on Solaris
partition_myisam     ; Different error on Solaris

Some other failures in mroonga was because have_32bit.inc didn't correctly
detect 64 bits on Solaris. Fixed using DEFAULT_MACHINE instead of MACHINE_TYPE
for Sys_version_compile_machine.

feedback plugin needs to set tables->select_lex properly

make it possible to change feedback plugin wait intervals
* only in debug builds
* and force the feedback report to be ignored

update the test to use this feature

In domain ID based filtering, a flag is used to filter-out
the events that belong to a particular domain. This flag gets
set when IO thread receives a GTID_EVENT for the domain on
filter list and its reset at the last event in the GTID group.
The resetting, however, was wrongly done before the decision to
write/filter the event from relay log is made. As a result, the
last event in the group will always pass through the filter.
Fixed by deferring the reset logic. Also added a test case.

  Turn the 'abort_on_warning' on for assigning value to fields.

fix it only for local operations.
