- Make Rdb_binlog_manager::unpack_value to not have a stack overrun
  when it is reading invalid data (which it currently does as we in
  MariaDB do not store binlog coordinates under BINLOG_INFO_INDEX_NUMBER,
  see comments in MDEV-14892 for details).
- We may need to store these coordinates in the future, so instead of
  removing the call of this function, let's make it work properly for
  all possible inputs.

The warning was originally added in
commit c6766305
(MySQL 4.1.12, 5.0.3) to trace claimed undo log corruption that
was analyzed in https://lists.mysql.com/mysql/176250
on November 9, 2004.

Originally, the limit was 20,000 undo log headers or transactions,
but in commit 9d6d1902
in MySQL 5.5.11 it was increased to 2,000,000.

The message can be triggered when the progress of purge is prevented
by a long-running transaction (or just an idle transaction whose
read view was started a long time ago), by running many transactions
that UPDATE or DELETE some records, then starting another transaction
with a read view, and finally by executing more than 2,000,000
transactions that UPDATE or DELETE records in InnoDB tables. Finally,
when the oldest long-running transaction is completed, purge would
run up to the next-oldest transaction, and there would still be more
than 2,000,000 transactions to purge.

Because the message can be triggered when the database is obviously
not corrupted, it should be removed. Heavy users of InnoDB should be
monitoring the "History list length" in SHOW ENGINE INNODB STATUS;
there is no need to spam the error log.

- Skip 'clean' if not a git repository
  (Good for tar files)
- Add configuration for ASAN builds

Roll back to most general duplicate removing strategi in case of different stratagies for one position.

Replace most occurrences of the REFMAN macro. For some pages there
is no replacement yet.

recv_log_recover_10_3(): Determine if a log from MariaDB 10.3 is clean.

recv_find_max_checkpoint(): Allow startup with a clean 10.3 redo log.

srv_prepare_to_delete_redo_log_files(): When starting up with a 10.3 log,
display a "Downgrading redo log" message instead of "Upgrading".

Backport the fix from 10.0.33 to 5.5, in case someone compiles XtraDB
with -DUNIV_LOG_ARCHIVE

The XtraDB option innodb_track_changed_pages causes
the function log_group_read_log_seg() to be invoked
even when recv_sys==NULL, leading to the SIGSEGV.

This regression was caused by
MDEV-11027 InnoDB log recovery is too noisy

is set to ERR

This matches gcc/clang handling.

with recursive reference in subquery

If a recursive CTE uses a subquery with recursive reference then
the virtual function reset() must be called after each iteration
performed at the execution of the CTE.

innodb/buf_LRU_get_free_block
	Add debug instrumentation to produce error message about
	no free pages. Print error message only once and do not
	enable innodb monitor.

xtradb/buf_LRU_get_free_block
	Add debug instrumentation to produce error message about
	no free pages. Print error message only once and do not
	enable innodb monitor. Remove code that does not seem to
	be used.

innodb-lru-force-no-free-page.test
	New test case to force produce desired error message.

row_insert_for_mysql(): Remove some duplicated code

dict_foreign_find_index(): Ignore incompletely created indexes.
After a failed ADD UNIQUE INDEX, an incompletely created index
could be left behind until the next ALTER TABLE statement.
