MDEV-27557 InnoDB unnecessarily commits mtr during secondary index search to preserve clustered index latching order

New function to release latches till savepoint was added in mtr_t. As there is
no longer need to limit MDEV-20605 fix usage for locking reads only, the
limitation is removed.

MDEV-27909 InnoDB: Failing assertion: state == TRX_STATE_NOT_STARTED ... on DDL

The fix in commit 6e390a62baa9dfd92d2776d28c97fd9525422295 (MDEV-26772)
was a step to the right direction, but implemented incorrectly.
When an InnoDB persistent statistics table cannot be locked immediately,
we must not let row_mysql_handle_errors() to roll back the transaction.

lock_table_for_trx(): Add the parameter no_wait (default false)
for an immediate return of DB_LOCK_WAIT in case of a conflict.

ha_innobase::delete_table(), ha_innobase::rename_table():
Pass no_wait=true to lock_table_for_trx() when needed,
instead of temporarily setting THDVAR(thd, lock_wait_timeout) to 0.

MDEV-17841 fixup: GCC -Wmaybe-uninitialized

In commit ab38b7511bad8cc03a67f0d43e7169e6dfcac9fa
an added "goto err" would seemingly cause a read of
an uninitialized variable old_info if errpos>=5.

However, because we would have errpos=0 at that point,
there was no real error.

MDEV-28079 Shutdown hangs after altering innodb partition fts table

- InnoDB purge waits at resume_FTS() while shutting down.
This happens after altering the FTS innodb partition table.
stop_FTS() has been called for each partition, but it calls
resume_FTS() only once and it leads to hang during shutdown.
This issue was introduced by
commit 1bd681c8b3c5213ce1f7976940a7dc38b48a0d39(MDEV-25506).
