Jan Lindström da3a3a68df MDEV-12837: WSREP: BF lock wait long
Problem was a merge error from MySQL wsrep i.e. Galera.

wsrep_on_check
	New check function. Galera can't be enabled
	if innodb-lock-schedule-algorithm=VATS.

innobase_kill_query
	In Galera async kill we could own lock mutex.

innobase_init
	If Variance-Aware-Transaction-Sheduling Algorithm (VATS) is
	used on Galera we fall back to First-Come-First-Served (FCFS)
	with notice to user.

Changed innodb-lock-schedule-algorithm as read-only parameter
as it was designed to be.

lock_reset_lock_and_trx_wait
	Use ib::hex() to print out transaction ID.

lock_rec_other_has_expl_req,
lock_rec_other_has_conflicting,
RecLock::add_to_waitq
lock_rec_lock_slow
lock_table_other_has_incompatible
lock_rec_insert_check_and_lock
lock_prdt_other_has_conflicting

	Change pointer to conflicting lock to normal pointer as this
	pointer contents could be changed later.

RecLock::create
	Conclicting lock pointer is moved to last parameter with
	default value NULL. This conflicting transaction could
	be selected as victim in Galera if requesting transaction
	is BF (brute force) transaction. In this case contents
	of conflicting lock pointer will be changed. Use ib::hex() to print
	transaction ids.
