This fixes a race condition in the test system
mysql-test/include/maria_empty_logs.inc:
Added comment
mysql-test/include/wait_for_status_var.inc:
Fixed type in variable name. Add ' around variables for better error message
mysql-test/mysql-test-run.pl:
Remove -skip-falcon (not to be used), add skip-pbxt to bootstrap
mysql-test/suite/maria/t/maria_showlog_error-master.opt:
Force restart before maria_showlog_error to get rid of status from previous connection
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.
