Log:
libc MT-safety, part 2.
Add a lock to FILE. flockfile and friends are now implemented
(for the most part) in libc. flockfile_debug is implemented in
libc_r; I suppose it's about time to kill it but will do it in
a future commit.
Fix a potential deadlock in _fwalk in a threaded environment.
A file flag (__SIGN) was added to stdio.h that, when set, tells
_fwalk to ignore it in its walk. This seemed to be needed in
refill.c because each file needs to be locked when flushing.
Add a stub for pthread_self in libc. This is needed by flockfile
which is allowed by POSIX to be recursive.
Make fgetpos() error return value (-1) match man page.
Remove recursive calls to locked functions (stdio); I think I've
got them all, but I may have missed a couple.
A few K&R -> ANSI conversions along with removal of a few instances
of "register".
$Id$ -> $FreeBSD$ in libc/stdio/rget.c
Not objected to: -arch, a few months ago
