Add a _REENT_ERRNO() macro to encapsulate the access to the
_errno member of struct reent. This will help to replace the
structure member with a thread-local storage object in a follow
up patch.
Replace uses of __errno_r() with _REENT_ERRNO(). Keep __errno_r() macro for
potential users outside of Newlib.
These source files have makedoc markup, but aren't listed to be chewed by
makedoc. I am assuming that is accidental.
Future work: Note that stdio/fseeko.c, stdio/ftello.c and common/s_isnand.c have
makedoc markup, but duplicate stdio/fseek.c, stdio/ftell.c and common/s_isnan.c
respectively.

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.
