MariaDB will likely never support MySQL-style encryption for
InnoDB, because we cannot link with the Oracle encryption plugin.
This is preparation for merging MDEV-11623.
fil_space_crypt_cleanup(): Call mutex_free() to pair with
fil_space_crypt_init().
fil_space_destroy_crypt_data(): Call mutex_free() to pair with
fil_space_create_crypt_data() and fil_space_read_crypt_data().
fil_crypt_threads_cleanup(): Call mutex_free() to pair with
fil_crypt_threads_init().
fil_space_free_low(): Invoke fil_space_destroy_crypt_data().
fil_close(): Invoke fil_space_crypt_cleanup(), just like
fil_init() invoked fil_space_crypt_init().
Datafile::shutdown(): Set m_crypt_info=NULL without dereferencing
the pointer. The object will be freed along with the fil_space_t
in fil_space_free_low().
Remove some unnecessary conditions (ut_free(NULL) is OK).
srv_shutdown_all_bg_threads(): Shut down the encryption threads
by calling fil_crypt_threads_end().
srv_shutdown_bg_undo_sources(): Do not prematurely call
fil_crypt_threads_end(). Many pages can still be written by
change buffer merge, rollback of incomplete transactions, and
purge, especially in slow shutdown (innodb_fast_shutdown=0).
innobase_shutdown_for_mysql(): Call fil_crypt_threads_cleanup()
also when innodb_read_only=1, because the threads will have been
created also in that case.
sync_check_close(): Re-enable the invocation of sync_latch_meta_destroy()
to free the mutex list.

Unlike MySQL, InnoDB still uses THR_LOCK in MariaDB

MDEV-10547: Test multi_update_innodb fails with InnoDB 5.7
The failure happened because 5.7 has changed the signature of
the bool handler::primary_key_is_clustered() const
virtual function ("const" was added). InnoDB was using the old
signature which caused the function not to be used.
MDEV-10550: Parallel replication lock waits/deadlock handling does not work with InnoDB 5.7
Fixed mutexing problem on lock_trx_handle_wait. Note that
rpl_parallel and rpl_optimistic_parallel tests still
fail.
MDEV-10156 : Group commit tests fail on 10.2 InnoDB (branch bb-10.2-jan)
Reason: incorrect merge
MDEV-10550: Parallel replication can't sync with master in InnoDB 5.7 (branch bb-10.2-jan)
Reason: incorrect merge
