Disabling and enabling indexes on a non-empty table grows the
index file.
Disabling indexes just sets a flag per non-unique index and does not
free the index blocks of the affected indexes. Re-enabling indexes
creates new indexes with new blocks. The old blocks remain unused
in the index file.
Fixed by dropping and re-creating all indexes if non-empty disabled
indexes exist when enabling indexes. Dropping all indexes resets
the internal end-of-file marker to the end of the index file header.
It also clears the root block pointers of every index and clears the
deleted blocks chains. This way all blocks are declared as free.
myisam/mi_check.c:
Bug#4692 - DISABLE/ENABLE KEYS waste a space
Added function mi_drop_all_indexes() to support drop of all indexes
in case we want to re-enable non-empty disabled indexes.
Changed mi_repair(), mi_repair_by_sort(), and mi_repair_parallel()
to use the new function instead of duplicate drop index code.

partitioned table
Trying INSERT DELAYED on a partitioned table, that has not been
used right before, crashes the server. When a table is used for
select or update, it is kept open for some time. This period I
mean with "right before".
Information about partitioning of a table is stored in form of
a string in the .frm file. Parsing of this string requires a
correctly set up lexical analyzer (lex). The partitioning code
uses a new temporary instance of a lex. But it does still refer
to the previously active lex. The delayd insert thread does not
initialize its lex though...
Added initialization for thd->lex before open table in the delayed
thread and at all other places where it is necessary to call
lex_start() if all tables would be partitioned and need to parse
the .frm file.

DELETE with a subquery in WHERE clause would sometimes ignore subquery
evaluation error and proceed with deletion.

If a stored function that contains a drop temporary table statement
is invoked by a create temporary table of the same name may cause
a server crash. The problem is that when dropping a table no check
is done to ensure that table is not being used by some outer query
(or outer statement), potentially leaving the outer query with a
reference to a stale (freed) table.
The solution is when dropping a temporary table, always check if
the table is being used by some outer statement as a temporary
table can be dropped inside stored procedures.
The check is performed by looking at the TABLE::query_id value for
temporary tables. To simplify this check and to solve a bug related
to handling of temporary tables in prelocked mode, this patch changes
the way in which this member is used to track the fact that table is
used/unused. Now we ensure that TABLE::query_id is zero for unused
temporary tables (which means that all temporary tables which were
used by a statement should be marked as free for reuse after it's
execution has been completed).

sql/sql_base.cc:
Changed the approach to distinguishing currently unused temporary tables.
Now we ensure that such tables always have TABLE::query_id set to 0 and
use this fact to perform checks during opening and dropping of temporary
tables. This means that we have to call close_thread_tables() even for
statements which use only temporary tables. To make this call cheaper,
we re-factored close_thread_tables() to not take LOCK_open unless there
are open base tables.
sql/sql_handler.cc:
Properly close temporary tables associated with a handler.
sql/sql_insert.cc:
close_temporary_table is now merged into drop_temporary_table.
sql/sql_parse.cc:
Now the condition doesn't cover all cases because close_thread_tables()
must be called even for statements that use only temporary tables.

Use drop_temporary_table which perform checks to verify if
the table is not being used. Error path problem is due to
a handler tables issue and is going to be addressed in bug
31397.

Rename previously unused clear_query_id and document the usage of

The mysql_change_user command fails to properly update the database pointer
when no database is selected, leading to "use after free" errors. The same
happens on the user privilege pointer in the thread security context.
The solution is to properly reset and update the database name. Also update
the user_priv pointer so that it doesn't point to freed memory.
