The issue was that we sent two different signals to different threads
after each other. The DEBUG_SYNC functionality cannot handle this (as
the signal is stored in a global variable) and the first one can get
lost.
Fixed by using the same signal for both threads.
As a part of this MDEV following changes were made:
1) Mariadb named executables used instead of mysql named executables in scripts
2) renamed mysql-test-run and mysql-stress-test to mariadb-test-run and
mariadb-stress-test and created a symlink.
When acquiring SNW/SNRW/X MDL lock DDL/admin statements may abort pending
thr lock in concurrent connection with open HANDLER (or delayed insert
thread).
This may lead to a race condition when table->alias is accessed
concurrently by such threads. Either assertion failure or memory leak
is a practical consequence of this race condition.
Specifically HANDLER is opening a table and issuing alias.copy(), while
DDL executing get_lock_data()/alias.c_ptr()/realloc()/realloc_raw().
Fixed by perforimg table->init() before it is published via
thd->open_tables.
Quick fix: run mysql-stress-test.pl via a wrapper test
Amend mtr to run just that test when using --stress
Updated mysql-stress-test.pl to exit(1) if wrong options
into trift2.:/MySQL/M51/push-5.1

BitKeeper/etc/ignore:
Added mysql-test/.DS_Store .DS_Store to the ignore list
mysql-test/t/disabled.def:
Disabled new test - csv_alter_table.test file due to Bug#33696.
Cannot generate a .result file due to the Bug. These tests can be enabled to test the bug fix without needing new tests unless the developer feels the need to add more.

New tests added for Bug#33558 - Test "stress.ddl_csv needs nullable columns which CSV does not support
mysql-test/t/csv_alter_table.test:
New tests added for Bug#33558 - Test "stress.ddl_csv needs nullable columns which CSV does not support
Designed to test fixes for Bug#33696 - CSV Engine allows nullable columns via ALTER TABLE statements
