Merge of r4933, r4933: shared memory fixes.
*) Fixed location of debug message in ngx_shmtx_lock().
*) Core: don't reuse shared memory zone that changed ownership (ticket #210).
nginx doesn't allow the same shared memory zone to be used for different
purposes, but failed to check this on reconfiguration. If a shared memory
zone was used for another purpose in the new configuration, nginx attempted
to reuse it and crashed.
