This will make it easier for us to try alternative mutex/condvar implementations while still using pthreads for thread management. [Feature #10134] * thread_pthread.h: define RB_NATIVETHREAD_LOCK_INIT and RB_NATIVETHREAD_COND_INIT macros * thread_pthread.c (native_mutex_lock, native_mutex_unlock, native_mutex_trylock, native_mutex_initialize, native_mutex_destroy, native_cond_wait): use rb_nativethread_lock_t instead of pthread_mutex_t * thread_pthread.c (native_mutex_debug): make argument type-agnostic to avoid later cast. * thread_pthread.c (register_cached_thread_and_wait): replace PTHREAD_COND_INITIALIZER with RB_NATIVETHREAD_COND_INIT, use native_mutex_{lock,unlock} * thread_pthread.c (use_cached_thread): use native_mutex_{lock,unlock} * thread_pthread.c (native_sleep): use rb_nativethread_lock_t to match th->interrupt_lock, use native_mutex_{lock,unlock} * thread_pthread.c (timer_thread_lock): use rb_nativethread_lock_t type git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@47185 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
