WL#3475 (Threads for the embedded server in mysqltest)

Necessary code added to mysqltest.c.
Disabled tests are available now.


client/mysqltest.c:
  do_send_query function implemented, so now 'send' command will be
  run in separate thread for the embedded server.
  Mutex and condition added to the 'connection' struct for syncronisation
  purposes. Yes it'd be easier if we had pthread_join() command
libmysql/libmysql.c:
  this isn't actually needed and causes problems in embedded server
mysql-test/t/bdb-deadlock.test:
  test is available for the embedded server now
mysql-test/t/flush.test:
  test is available for the embedded server now
mysql-test/t/flush_block_commit.test:
  test is available for the embedded server now
mysql-test/t/innodb-deadlock.test:
  test is available for the embedded server now
mysql-test/t/innodb-lock.test:
  test is available for the embedded server now
mysql-test/t/lock_multi.test:
  test is available for the embedded server now
mysql-test/t/rename.test:
  test is available for the embedded server now
mysql-test/t/show_check.test:
  test is available for the embedded server now
mysql-test/t/status.test:
  test is available for the embedded server now
