5.5.13-eb multiple valgrind warnings

[Valentine Gostev]

As agreed I am reporting here total list of valgrin warnings discovered. So later they could be forked into separate reports if necessary.

Failing tests with valgrind: (excluding failures from upstream)

I have pushed the fix that should fix a very big part (but not all) of failures. Can you re-run the testsuite? Hopefully the remaining failures will be easy to group now.

[Valentine Gostev (longbow)]

Laurynas,
few of them left

main.heap_bug783366
main.kill
main.sp-threads
sys_vars.thread_cache_size_func
perfschema.func_file_io
perfschema.func_mutex
perfschema.global_read_lock

How do I reproduce Valgrind errors with these? I tried ./mysql-test-run.pl --mem --mysqld=--thread_handling=pool-of-threads --valgrind <test-name>, and they all come valgrind-clean.

In any case, these test failures have their own bugs, so if there are any valgrind failures, let's add them to those bugs.

If heap_bug783366 fails for you, please reopen that bug.
The rest are already tracked, in the order of tests: #782106 #780473 #780502 #780722 #781035 #781065 #781069 #781075 #781092
