Log message:
	* libc/stdio/local.h (_newlib_flockfile_start): New macro to
	secure stream related critical section against thread cancellation.
	(_newlib_flockfile_exit): Ditto.
	(_newlib_sfp_lock_end): Ditto.
	(_newlib_sfp_lock_start): Ditto for the list of streams.
	(_newlib_sfp_lock_exit): Ditto.
	(_newlib_sfp_lock_end): Ditto.
	Use aforementioned macros in place of _flockfile/_funlockfile
	and __sfp_lock_acquire/__sfp_lock_release throughout the code.
	* libc/stdio/fclose.c: Explicitely disable and re-enable thread
	cancellation.  Explain why.
