thread_pthread: prefer rb_nativethread* types/functions
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
