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
