- Move SAFE_MUTEX to be stored in config.h by configure.in (not as a flag used with compiler command line)
- Generate my_config.h in configure

BUILD/SETUP.sh:
  Remove -DSAFE_MUTEX as the following --with-debug flag will automaticly add it
BUILD/compile-ia64-debug-max:
  Remove -DSAFE_MUTEX as the following --with-debug flag will automaticly add it
configure.in:
  Move SAFE_MUTEX and SAFE_MALLOC to [my_] config.h
  Generate my_config.h as part of configure process
dbug/dbug.c:
  Include my_global.h before we undef SAFE_MUTEX
include/Makefile.am:
  Update comment. For now, lets generate my_config.h if someone deletes it after configure
mysys/my_wincond.c:
  Include my_global.h before we undef SAFE_MUTEX
mysys/my_winthread.c:
  Include my_global.h before we undef SAFE_MUTEX

mysqld w/ --valgrind

 - Fixed by implementing parsing of error log messages generated outside of
   test case runs (eg. during server shutdown).

Also make mysql-test-run.pl not delete the error log after server restart,
which looses information about which warnings were found.

Finally, make multi_update2 a --big test.

mysql-test/lib/My/Test.pm:
  Fix home-brewed (and broken) serialization in My::Test to use the standard
  Storable serializer.
mysql-test/mysql-test-run.pl:
   - Stop mysqld servers gracefully rather than kill -9 when
     warnings are being checked.
  
   - After stopping mysqld servers, do an additional parse of the error
     log to check for any warnings generated during shutdown.
    
   - Fix error log parsing to be careful not to skip parsing part of the
     file, by keeping track of previous file position rather than
     relying on mark_log markers.
  
   - Workers report warnings during shutdown to the master process with
     a new packet 'WARNINGS' which includes a list of names of test that
     might have caused the problem (could be any test run since last
     server start).
    
   - Fail entire test suite if warnings are found.
  
   - When we remove the server data dir before server restart, preserve the
     error log (don't delete it between restarts), as it may contain
     valuable information even for test cases which don't show direct
     failures.
mysql-test/t/multi_update2.test:
  Make test --big, as it takes a _long_ time to run and only tests a single bug.

include/config-win.h:
  Added missing typedef ssize_t
  Added some other useful defines from MySQL 6.0
unittest/mysys/waiting_threads-t.c:
  Fixed link failure for 'ftruncate' on Windows

The additional test uses up all threads in the pool with SELECT
SLEEP(), and tests that this makes normal connections block, but
connections on the extra port still work.

Also test connection limit on extra port with and without
pool-of-threads enabled.

Add --connect-timeout option to mysqltest program.

Add facility for --extra-port option to ConfigFactory.

Fix regexp typo in ConfigFactory.pm

Fixed compiler error when configuring without --lib-event

include/mysql_version.h.in:
  Added mariadb-'version' as a my.cnf option tag for mysqld
sql/mysqld.cc:
  Added mariadb and mariadb-version as my.conf option tags

storage/maria/ma_loghandler.c:
  Fixed bug of waiting for flush pass end: in case of two sequential flushes waiting thread can not detect end of the pass it is waiting because till the time it will check the flush in progress flag will be set on again. Solution is to have pass number and compare the number before before waits start and check it as condition of the flush pass end (of course it does not matter if the counter of pass number overflows).

Remove non-source file from bzr.

This is a backport of code from MySQL 6.0 with cleanups and extensions

The following new options are supported
configure options:
  --with-libevent                  ; Enable use of libevent, which is needed for pool of threads

mysqld options:
--thread-handling=pool-of-threads  ; Use a pool of threads to handle queries
--thread-pool-size=#               ; Define how many threads should be created to handle all queries
--extra-port=#                     ; Extra tcp port that uses the old one-thread-per-connection method
--extra-max-connections=#          ; Number of connections to accept to 'extra-port'
--test-ignore-wrong-options        ; Ignore setting an enum value to a wrong option (for mysql-test-run)

- adding back Serg's "mtr --list-options"
- safe_mutex deadlock detector started raising wrong deadlock warnings, fixed
here by a backport from 6.0-main.

include/my_pthread.h:
  Porting changes done to 6.0-main which satisfy the safe_mutex deadlock detector (those
  in 5.1-main don't), see chad@mysql.com-20090126155607-n0j3zbmgbfepnmmo for explanations
mysql-test/mysql-test-run.pl:
  adding back Serg's --list-options
mysys/my_init.c:

mysys/my_thr_init.c:

There were so many changes into mtr (this is the new mtr coming) that I rather
copied mtr from 6.0-main here (at least this one knows how to run Maria tests).
I also fixed suite/maria tests to be accepted by the new mtr.

mysys/thr_mutex.c:
  adding DBUG_PRINT here, so that we can locate where the warning is issued.

it was bug in a test program, changed WT_THD's initialization to ensure they have no garbage from the previous run.

Assert that keys don't point to bitmap pages.

storage/maria/ma_blockrec.h:
  assertion
storage/maria/ma_locking.c:
  With concurrent INSERTs, it is possible that two threads enter _ma_mark_file_changed()
  at the same time, so they should serialize their access to the "changed" state/share
  members; another reason is that this function may call _ma_update_state_lsns_sub()
  which may call translog_deassign_id_from_share() (I saw it during testing of
  online backup) which requires the intern_lock mutex.
  As INSERTs only change from "not changed" to "changed", we can first check without mutex:
  if it says "changed", some other thread has set or is setting the variables now,
  we don't need to do it; if it says "not changed", we serialize and re-check.
