* 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.
