* include/sys/strace.h: Define _STRACE_SPECIAL.

Browse Source 
(strace_printf_wrap): Fix NOSTRACE definitions.
(strace_printf_wrap1): Fix NOSTRACE definitions.
(special_printf): Define.
* thread.cc: Perform minor syntax fix in a comment.  Rename
"is_good_initialzer*" to "is_initializer*" throughout.  Use pthread_printf
rather than debug_printf throughout.  Add extra pthread_printf debugging
throughout.
(pthread_mutex::_new_mutex): New constant value.
(pthread_mutex::_unlocked_mutex): Ditto.
(pthread_mutex::_destroyed_mutex): Ditto.
(pthread_mutex::no_owner): Define new function.
(pthread_mutex::can_be_unlocked): Detect no_owner situation.  Handle
PTHREAD_MUTEX_NORMAL as a special case.
(pthread::create_cancel_event): Use C++ boolean values.
(pthread::precreate): Use method to set mutex type.
(pthread_cond::pthread_cond): Ditto.
(pthread_rwlock::pthread_rwlock): Ditto.
(pthread_mutex::pthread_mutex): Set owner to _new_mutex initially.
(pthread_mutex::~pthread_mutex): Reset various elements to make it clearer if
they are incorrectly reused.
(pthread_mutex::lock): Add clarifying comment.
(pthread_mutex::unlock): Attempt to handle various mutex types correctly.  In
particular, reinstate ability to have one thread unlock another thread's mutex
if type == PTHREAD_MUTEX_NORMAL.
(semaphore::_fixup_after_fork): Avoid redundancy.
(pthread_mutex::_fixup_after_fork): Ditto.  Fix debugging statement.
(__pthread_cond_dowait): Accommodate changes to remove previously inexplicable
use can_be_unblocked() as a static function.
* thread.h: Rename "is_good_initialzer*" to "is_initializer*" throughout.
(pthread_mutex): Reorganize.  Make many things private.
(pthread_mutex::no_owner): Define new method.
(pthread_mutex::_new_mutex): Define new constant.
(pthread_mutex::_unlocked_mutex): Ditto.
(pthread_mutex::_destroyed_mutex): Ditto.
