Log message:

	* libc/stdio/fclose.c (fclose): Protect file pointer list when
	releasing a file.
	* libc/stdio/fcloseall.c (_fcloseall_r): Close all files via
	fwalk.
	* libc/stdio/fdopen.c (_fdopen_r): Add calls to
	_flockfile/_funlockfile.
	* libc/stdio/findfp.c: Move __sfp_lock. Change __sfp_lock type
	to recursive.
	Change __lock_acquire/__lock_release calls for __sfp_lock to
	__sfp_lock_acquire/__sfp_lock_release throughout.
	(std): Make sure that file lock is only initialized once.
	(__sfp): Move _file initialization. Initialize file lock.
	(__sfp_lock_acquire): New function.
	(__sfp_lock_release): Ditto.
	(__fp_lock_all): Remove __sfp_lock_acquire call.
	(__fp_unlock_all): Remove __sfp_lock_release call.
	* libc/stdio/fopen.c (_fopen_r): Protect file pointer list.
	Add calls to _flockfile/_funlockfile. Remove
	__lock_init_recursive call.
	* libc/stdio/freopen.c (_freopen_r): Protect file pointer list.
	* libc/stdio/fwalk.c (__fwalk): New static function.
	(_fwalk): Protect file pointer list. Use __fwalk to walk through
	file pointers.
	* libc/stdio/local.h: Add defines for
	__sfp_lock_acquire/__sfp_lock_release when
	single threaded. Add function prototypes otherwise.
	* libc/stdio64/fdopen64.c (_fdopen64_r): Add calls to
	_flockfile/_funlockfile.
	* libc/stdio/fopen64.c (_fopen64_r): Protect file pointer list.
	Add calls to _flockfile/_funlockfile. Remove
	__lock_init_recursive call.
	* libc/stdio/freopen64.c (_freopen64_r): Protect file pointer
	list.
