1d8053c5c0 Renumber clauses to reduce diffs to other versions
NetBSD, OpenBSD, and Android's Bionic all number the clauses 1 through 3,
so follow suit to make comparison easier.

19e03ca803 Expose FILE's internals to the world again in all their glory. Restore
all the previous inline optimizations as well.  FILE is back to using
__mbstate_t, struct pthread *, and struct pthread_mutex *.

c17bf9a9a5 Next round of stdio changes: Remove all inlining of stdio operations and
move the definition of the type backing FILE (struct __sFILE) into an
internal header.
- Remove macros to inline certain operations from stdio.h.  Applications
  will now always call the functions instead.
- Move the various foo_unlocked() functions from unlocked.c into foo.c.
  This lets some of the inlining macros (e.g. __sfeof()) move into
  foo.c.
- Update a few comments.
- struct __sFILE can now go back to using mbstate_t, pthread_t, and
  pthread_mutex_t instead of knowing about their private, backing types.

567d74a5ec Re-add macro versions of getc(), getchar(), putc(), putchar(), feof(),
ferror(), fileno() and clearerr(), using the value of __isthreaded to
decide between the fast inline single-threaded code and the more
general function equivalent. This gives most of the performance
benefits of the old unsafe macros while preserving thread safety.

333fc21e3c Fix the style of the SCM ID's.
I believe have made all of libc .c's as consistent as possible.

29ac6bd228 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".

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

Added $Id$'s to files that were lacking them (gpalmer), made some
cosmetic changes to conform to style guidelines (bde) and checked
against NetBSD and Lite2 to remove unnecessary divergences (hsu, bde)

One last code cleanup:-

Removed spurious casts in fseek.c and stdio.c.
Added missing function argument in fwalk.c.
Added missing header include in flags.c and rget.c.
Put in casts where int's were being passed as size_t's.
Put in missing prototypes for static functions.
Changed second args of __sflags() inflags.c and writehook() in vasprintf.c
from char * to const char * to conform to prototypes.

This directory now compiles with no warnings with -Wall under
gcc-2.6.3 and with considerably less warnings than before with the
ultra-pedantic script I used for testing. (Most of the remaining ones
are due to const poisoning).

e2f892a7e7 Code cleanup:-
The usual stuff, adding missing function prototypes, argument types,
return values, etc.
