  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
