unknown 719e64e4a5 Bug#32528 Global read lock with a low priority write lock causes a server crash 
FLUSH TABLES WITH READ LOCK fails to properly detect write locked
tables when running under low priority updates.

The problem is that when trying to aspire a global read lock, the
reload_acl_and_cache() function fails to properly check if the thread
has a low priority write lock, which later my cause a server crash or
deadlock.

The solution is to simple check if the thread has any type of the
possible exclusive write locks.


mysql-test/r/flush.result:
  Add test case result for Bug#32528
mysql-test/t/flush.test:
  Add test case for Bug#32528
sql/sql_parse.cc:
  Although it should not matter under LOCK TABLES, use TL_WRITE_ALLOW_WRITE
  to emphasize that it should fail in case of any write lock.
