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.
