Don't try to be smart about --socket.
Assume that if user has set up a non-standard location for a socket,
she did it consistently for both a server and clients
(otherwise most clients won't work anyway).

        The RTLD_DEFAULT value on Labrador machine is not NULL,
        so the dlsym() commands in the server_audit just fail
        to bind the necessary functions.
        Fixed by using RTLD_DEFAULT explicitly.

mysql-test/suite/rpl/t/rpl_000011-slave.opt:
  Renamed test case as it's slave that needs to restarted
support-files/compiler_warnings.supp:
  Fixed bad characters in suppression

mysql-test/suite/rpl/t/rpl_000011-master.opt:
  Added master.opt file to ensure that other tests don't interfere with rpl_000011
plugin/server_audit/server_audit.c:
  Fixed compiler error on solaris
support-files/compiler_warnings.supp:
  Ignore warning from xtradb

   Notifications about changed variables:
              server_audit_file_rotate_now
              server_audit_file_rotations
              server_audit_file_rotations
   are now handled and one doesn't need to stop/start logging to make them effective.

Reason for the bug was an optimization for higher connect speed where we moved when global status was updated,
but forgot to update states when slave thread dies.
Fixed by adding thd->add_status_to_global() before deleting slave thread's thd.


mysys/my_delete.c:
  Added missing newline
sql/mysqld.cc:
  Use add_status_to_global()
sql/slave.cc:
  Added missing add_status_to_global()
sql/sql_class.cc:
  Use add_status_to_global()
sql/sql_class.h:
  Simplify adding local status to global by adding add_status_to_global()

MDEV-5446: Assertion `!table || (!table->read_set || bitmap_is_set(table->read_set, field_index))' fails on EXPLAIN EXTENDED with VALUES function

field_index should be set correctly for null field created by Item_insert_value::fix_fields().

(as it's done in 10.0)

Item_default_value::arg can be NULL so walk() should take it into consideration.

Item_default_value::arg can be NULL so walk() should take it into consideration.

MDEV-5740: Assertion `!derived->first_select()->exclude_from_table_unique_test || derived->outer_select()-> exclude_from_table_unique_test' failed on 2nd execution of PS with derived_merge

Do not check tables of executed units.
Debug info about stages of derived tables execution added.

The calls of the function remove_eq_conds() may change the and/or structure
of the where conditions. So JOIN::equal_cond should be updated for non-recursive
calls of remove_eq_conds(). 

(assert added by MySQL verified that strnxfrm can only *increase*
the string length if from == to, and the latter is a random
decision made by individual items and String::realloc).

Fix it by avoiding the memcpy in the first place.

initialize it for full gc if we think it is worth it. This allows for
full gc to run when bringing a basement node up to date.

there may be an abort message waiting to be applied.
