Part of fix for bug#52044 "FLUSH TABLES WITH READ LOCK and 

FLUSH TABLES <list> WITH READ LOCK are incompatible" to
be pushed as separate patch.

Replaced thread state name "Waiting for table", which was
used by threads waiting for a metadata lock or table flush, 
with a set of names which better reflect types of resources
being waited for.

Also replaced "Table lock" thread state name, which was used 
by threads waiting on thr_lock.c table level lock, with more
elaborate "Waiting for table level lock", to make it 
more consistent with other thread state names.

Updated test cases and their results according to these 
changes.

Fixed sys_vars.query_cache_wlock_invalidate_func test to not
to wait for timeout of wait_condition.inc script.
