an two more queries were added, and removed a
query that produces a wrong result due to an
unrelated problem. The wrong result is submitted
as a separate bug.

ASSERTION TABLE->DB_STAT FAILED IN
SQL_BASE.CC::OPEN_TABLE() DURING I_S Q
This assert could be triggered if a statement requiring a name
lock on a table (e.g. DROP TRIGGER) executed concurrently
with an I_S query which also used the table.
One connection first started an I_S query that opened a given table.
Then another connection started a statement requiring a name lock
on the same table. This statement was blocked since the table was
in use by the I_S query. When the I_S query resumed and tried to
open the table again as part of get_all_tables(), it would encounter
a table instance with an old version number representing the pending
name lock. Since I_S queries ignore version checks and thus pending
name locks, it would try to continue. This caused it to encounter
the assert. The assert checked that the TABLE instance found with a
different version, was a real, open table. However, since this TABLE
instance instead represented a pending name lock, the check would
fail and trigger the assert.
This patch fixes the problem by removing the assert. It is ok for
TABLE::db_stat to be 0 in this case since the TABLE instance can
represent a pending name lock.
Test case added to lock_sync.test.

FAILS IN SET_FIELD_ITERATOR
(Former 59299)
When a PROCEDURE does a natural join, resolving of which columns are
used in the join is done only once; consecutive CALLs to the procedure
will reuse this information:
CREATE PROCEDURE proc() SELECT * FROM t1 NATURAL JOIN v1;
CALL proc(); <- natural join columns resolved here
CALL proc(); <- reuse resolved NJ columns from first CALL
The second CALL knows that it can reuse the resolved NJ columns because
the first CALL sets st_select_lex::first_natural_join_processing=false.
The problem in this bug was that the table the view v1 depends on
changed between CREATE PROCEDURE and the first CALL:
CREATE PROCEDURE...
ALTER TABLE t2 CHANGE COLUMN a b CHAR;
CALL proc(); <- error when resolving natural join columns
CALL proc(); <- tries to reuse from first CALL => crash
The fix for this bug is to set first_natural_join_processing= FALSE iff
the natural join columns resolving was successful.

FLUSH TABLES under FLUSH TABLES <list> WITH READ LOCK leads
to assert failure.
This assert was triggered if a statement tried up upgrade a metadata
lock with an active FLUSH TABLE <list> WITH READ LOCK. The assert
checks that the connection already holds a global intention exclusive
metadata lock. However, FLUSH TABLE <list> WITH READ LOCK does not
acquire this lock in order to be compatible with FLUSH TABLES WITH
READ LOCK. Therefore any metadata lock upgrade caused the assert to
be triggered.
This patch fixes the problem by preventing metadata lock upgrade
if the connection has an active FLUSH TABLE <list> WITH READ LOCK.
ER_TABLE_NOT_LOCKED_FOR_WRITE will instead be reported to the client.
Test case added to flush.test.
