* sysdeps/mach/hurd/bits/libc-lock.h: New file, initially copied from
sysdeps/mach version. Implement counting ("recursive") mutexes
on top of cthreads mutexes.
* sysdeps/mach/hurd/bits/stdio-lock.h: File removed; generic now works.
* sysdeps/generic/bits/stdio-lock.h (_IO_lock_initializer): Define to
_LIBC_LOCK_RECURSIVE_INITIALIZER if defined, else do an #error.
(__libc_cleanup_region_start, __libc_cleanup_region_end,
__libc_clean_end): Define these to call the cleanup function after
normal exit when they're supposed to.
* sysdeps/mach/bits/libc-lock.h (__libc_cleanup_region_start):
Take new first arg DOIT, a boolean saying whether to really install
any cleanup handler.
(__libc_cleanup_region_end): Do nothing if start's DOIT arg was zero.
(__libc_cleanup_end): Likewise.
* stdio-common/vfscanf.c (LOCK_STREAM): Pass new arg.
* stdio-common/vfprintf.c (buffered_vfprintf, vfprintf): Likewise.
* sysdeps/mach/hurd/bits/stdio-lock.h (_IO_cleanup_region_start):
Likewise.
* misc/syslog.c (vsyslog, openlog, closelog): Likewise.
* sysdeps/generic/bits/stdio-lock.h
(_IO_cleanup_region_start, _IO_cleanup_region_start_noarg): Likewise.
