  pthread-rwlock: Fix default wait queue behaviour on glibc/Linux.
  
  * lib/pthread.in.h: If REPLACE_PTHREAD_RWLOCK_INIT is 1 but
  REPLACE_PTHREAD_RWLOCK_DESTROY is 0, override
  PTHREAD_RWLOCK_INITIALIZER.
  * lib/pthread-rwlock.c
  (pthread_rwlockattr_init) [PTHREAD_RWLOCK_BAD_WAITQUEUE]: New function.
  (pthread_rwlock_init) [PTHREAD_RWLOCK_BAD_WAITQUEUE]: New function.
  * m4/pthread-rwlock.m4 (gl_PTHREAD_RWLOCK): Check for reasonable
  pthread_rwlock wait queue handling. Set REPLACE_PTHREAD_RWLOCK_INIT and
  REPLACE_PTHREAD_RWLOCKATTR_INIT and define PTHREAD_RWLOCK_BAD_WAITQUEUE
  if not.
  * modules/pthread-rwlock (configure.ac): Update
  GL_COND_OBJ_PTHREAD_RWLOCK condition.
  * doc/posix-functions/pthread_rwlock_rdlock.texi: Mark the glibc problem
  as fixed.
  * doc/posix-functions/pthread_rwlock_tryrdlock.texi: Likewise.
  * doc/posix-functions/pthread_rwlock_timedrdlock.texi: Likewise.
