pthread_mutex::init. * thread.cc: Remov some obsolete comments. (verifyable_object_isvalid): Reflect change to use thread_magic_t for magic numbers. (pthread_mutex::pthread_mutex): Set magic number to invalid initially until we've verified that everything is valid. (pthread_mutex::unlock): Fix a comment. (verifyable_object::verifyable_object): Delete here. (~verifyable_object::~verifyable_object): Ditto. (pthread_mutex::init): Don't run is_good_initializer for non-static objects. * thread.h (thread_magic_t): New typedef. (verifyable_object::verifyable_object): Use thread_magic_t; (verifyable_object::magic): Ditto. (pthread_mutex::is_good_initializer_or_bad_object): Remove unneeded variable names. (pthread_mutex::can_be_unlocked): Ditto. (pthread_mutex::init): Ditto. Remove default for third argument.
