Matt Joyce f3b8138239 Add _REENT_ERRNO(ptr)
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.

Corinna Vinschen 6e5b39940a newlib: ftello{64}: Handle appending stream without fflushing
Neither upstream FreeBSD nor glibc ever call fflush from ftell
and friends.  In border cases it has the tendency to return
wrong or unexpected values, for instance on block devices.

Corinna Vinschen dc2d175721 newlib: ftello{64}: Fix type of returned value
Especially don't just use -1L since _off_t/_off64_t are not
guaranteed to be of type long.
