Destroying rw_lock twice by resize() prevented.

The method Item_field::update_table_bitmaps() should not try
to mark the bit for a self-referencing virtual column.

- Let cleanup_empty_jtbm_semi_joins() walk into semi-join nests.

The field JOIN::select_lex->where should be updated after the call
of remove_eq_conds() in the function make_join_statistics(). This
matters for subselects.

Set of JOIN_TYPE_OUTER made only once to avoid interference with optimization joins which made only once per query.

It's wrong to return my_empty_string from val_str().
Removing my_empty_string. Using make_empty_result() instead.

            INSTALL PLUGIN

There was mixed lock order between LOCK_plugin, LOCK_global_system_variables
and LOCK_system_variables_hash. This patch ensures that write-lock on
LOCK_system_variables_hash doesn't intersect with LOCK_plugin.

Fixed by moving initialization/deinitialization of plugin options from
plugin_add()/plugin_del() to plugin_initialize()/plugin_deinitalize().
So that plugin options are handled without protection of LOCK_plugin.

add patch as a "suggested" dependency to mariadb-test-5.5

if two threads were calling mi_assign_to_key_cache() for the same table,
one could change share->key_cache while the other was having
share->key_cache->op_lock locked. The other thread would crash then,
trying to unlock share->key_cache->op_lock (because it would be a different mutex).

fixed by caching the value of share->key_cache in a local variable. The thread can still
call flush_key_blocks() for an unassigned keycache, but it's harmless.

Assertion `mon > 0 && mon < 13' failed.'

in some VMs readline thinks that the window size is zero. ignore it.

MDEV-5461 Assertion `length <= column->length' fails in write_block_record with functions in select list, GROUP BY, ORDER BY

Old code in create_tmp_table(), that created an extra one-byte field (recinfo)
before every NULL-able grouping field (Field) in the tmp table, did not actually work.
Because the matching code in end_update(), that was supposed to update this byte,
was using a wrong offset, updating the first byte of the Field, not a byte before it.
Normally this wasn't an issue, because the Field value (written later in end_update)
was overwriting this byte anyway. But in this bug the Field was Field_null, with zero
length, so end_update() was overwriting the first byte of the following field.
And the following field was not-nullable constant, which was stored only once in
create_tmp_table and never updated later.

Fixed by removing the code that didn't do any useful work anyway.

Added variable "OLD_MODE" that can be used to turn off the new behavior

  Cache old value of first_name_resolution_table for next call.
  (It's not safe to try to recalculate the value as the join structure may have been changed by the optimizer)

  Better error messages.
  Fixed wrong place for 'continue'

Marked very long running tests as big_test

Problem was that ALTER TABLE DISABLE KEYS incremented create_trid for the table,
which made the new index entries invisible until the global trid catched up.

Fixed by only updating create_trid if we are rewriting all rows and indexes.
