Replace MUTEX_INITIALIZER with _LIBC_LOCK_INITIALIZER in generic code
* sysdeps/mach/hurd/libc-lock.h (_LIBC_LOCK_INITIALIZER): Define. (__libc_lock_define_initialized): Use it. * sysdeps/nptl/libc-lockP.h (_LIBC_LOCK_INITIALIZER): Define. * malloc/arena.c (list_lock): Use _LIBC_LOCK_INITIALIZER. * malloc/malloc.c (main_arena): Likewise. * sysdeps/generic/malloc-machine.h (MUTEX_INITIALIZER): Remove. * sysdeps/nptl/malloc-machine.h (MUTEX_INITIALIZER): Remove.
