22-mutex-destroy-unlock: It seems that glibc assumes in its internal use of pthreads that destroying a lock implicity unlocks it. This patch handles this case so that lock ownership tracking is accurate. Also handles the case of the dyanmic linker wanting to do locking before Valgrind has started up. vg_libpthread now implements toy lock/unlock functions to keep it happy and leave the locks in a sensible state. Implements some untested code to handle the case where a lock is taken before Valgrind is running but released afterwards. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@1297
