Bug #26104 Bug on foreign key class constructor
Check that ref_columns is initalized correctly in the constructor
and semantic checks in mysql_prepare_table work.
We do not need a storage engine that supports foreign keys
for this test, as the checks are purely syntax-based, and the
syntax is supported for all engines.

Two latter cases indicate a request for lock upgrade.
XXX: why do we regard INSERT DELAYED into a view as an error and
do not simply a lock upgrade?
do not simply perform a lock upgrade?
TODO: The approach with using two mutexes to work with the
delayed thread list -- LOCK_delayed_insert and
LOCK_delayed_create -- is redundant, and we only need one of
them to protect the list. The reason we have two locks is that
we do not want to block look-ups in the list while we're waiting
for the newly created thread to open the delayed table. However,
this wait itself is redundant -- we always call get_local_table
later on, and there wait again until the created thread acquires
a table lock.
As is redundant the concept of locks_in_memory, since we already
have another counter with similar semantics - tables_in_use,
both of them are devoted to counting the number of producers for
a given consumer (delayed insert thread), only at different
stages of producer-consumer relationship.
'dead' and 'status' variables in Delayed_insert are redundant
too, since there is already 'di->thd.killed' and
di->stacked_inserts.
