Rip out the old __stdin/out/err stuff. It was completely 100% useless. :-(
It was foiled because of dynamic copy relocations that caused compile-time
space to be reserved in .bss and at run time a blob of data was copied to
that space and everything used the .bss version.. The problem is that
the space is reserved at compile time, not runtime... So we *still* could
not change the size of FILE. Sigh. :-(

Replace it with something that does actually work and really does let us
make 'FILE' extendable. It also happens to be the same as Linux does in
glibc, but has the slight cost of a pointer. Note that this is the
same cost that 'fp = fopen(), fprintf(fp, ...); fclose(fp);' has.
Fortunately, actual references to stdin/out/err are not all that common
since we have implicit stdin/out/err-using versions of functions
(printf() vs. fprintf()).

Place some hooks (__stdin, __stdout, __stderr) into libc for a future
ABI change. There is some serious evilness here to work around some
gcc weaknesses. We need to know the sizeof(FILE) manually until __sF
goes away in the next major bump. We have the size for Alpha and i386,
missing is ia64, ppc and sparc* (and i386 with 64 bit longs).
At some point down the track we can change the stdin etc #defines to
stop hard coding the size of FILE into application binaries.

Commit a libc fix going by the current state of the version numbering
bikeshed in -arch. It isn't quite over, but it has been well established
that this can be adjusted or refined. But we do seem to have consensis
on a major bump of some sort. After this, it should reasonably safe
to build world again.

This change is to get rid of __sF[] and use seperate __stdin/out/err
handles. This means we can pad on extra bits onto the end of FILE
at will without going through this all over again. __sF[] was evil
because it compiled the sizeof(FILE) into every stdio using program.

FILE *buffer = stdout;

Take advantage of the current libc sizeof(FILE) breakage (__sF[]) and
try a hopefully more robust stdin/stdout/stderr. This costs an indirect
pointer fetch, but saves us from changes in 'FILE'. The __stdin stuff
is there to not pollute application name space if the application does
not use <stdio.h> and also in case something depended on the current
behavior where stdin etc was a #define.

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".

Remove _THREAD_SAFE and make libc thread-safe by default by
adding (weak definitions to) stubs for some of the pthread
functions. If the threads library is linked in, the real
pthread functions will pulled in.

Use the following convention for system calls wrapped by the
threads library:
__sys_foo - actual system call
_foo - weak definition to __sys_foo
foo - weak definition to __sys_foo

Change all libc uses of system calls wrapped by the threads
library from foo to _foo. In order to define the prototypes
for _foo(), we introduce namespace.h and un-namespace.h
(suggested by bde). All files that need to reference these
system calls, should include namespace.h before any standard
includes, then include un-namespace.h after the standard
includes and before any local includes. <db.h> is an exception
and shouldn't be included in between namespace.h and
un-namespace.h namespace.h will define foo to _foo, and
un-namespace.h will undefine foo.

Try to eliminate some of the recursive calls to MT-safe
functions in libc/stdio in preparation for adding a mutex
to FILE. We have recursive mutexes, but would like to avoid
using them if possible.

Remove uneeded includes of <errno.h> from a few files.

Add $FreeBSD$ to a few files in order to pass commitprep.

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).
