Log message:
* dcrt0.cc (_dll_crt0): Set _main_tls as early as possible.
* thread.cc (pthread_mutex::can_be_unlocked): Remove check for
MUTEX_OWNER_ANONYMOUS since it is racy and unsafe.
(pthread::init_mainthread): Initialize thread directly from _my_tls.
(pthread::self): Ditto.
(pthread::get_tls_self_pointer): Delete.
(pthread_mutex::pthread_mutex): Use an event rather than a semaphore.
(pthread_mutex::lock): Rename from _<func>. Derive self directly.

event.
(pthread_mutex::_fixup_after_fork): Accommodate change from semaphore
to event.
