b0f8f42120 Extra needs to be initialized for our usual pool of FILEs. This was
causing some versions of as to dump core.  This survived make
buildworld/installworld and the building gettext port afterwards.

91e1be28dc Fix the current libc breakage in current:
o Back out the __std* stuff.  Can't figure out how to do this right now,
  so we'll save it for late.
o use _up as a pointer for extra fields that we need to access.
o back out the libc major version bump.

Submitted by: green
reviewed by: peter, imp, green, obrien (to varying degrees).

We'll fix the "how do we stop encoding sizeof(FILE) in binaries" part
later.

ff9dc074b5 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.

Asbestos suit on: check!
Peril sensitive sunglasses on: check!

56f98998e9 It sounded like a good idea at the time. The previous change breaks
FILE *buffer = stdout;
so back it out for now.

9b8ff47f40 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.

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".

d201fe46e3 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.

f1303ab4b2 Increase the size of the mktemp() filename space by dropping the PID from
the encoding and using the character set [a-zA-Z0-9]. This gives a total
of 62^6 = 56800235584 possible temporary filenames for the usual default
invocation of 6 X's (compared to as few as 52 possibilities for the
previous algorithm where up to 5 characters were wasted by the PID).

Update some apparently bitrotten comments to reflect reality.

9233c4d942 Simplify sytem call renaming. Instead of _foo() <-- _libc_foo <-- foo(),
just use _foo() <-- foo().  In the case of a libpthread that doesn't do
call conversion (such as linuxthreads and our upcoming libpthread), this
is adequate.  In the case of libc_r, we still need three names, which are
now _thread_sys_foo() <-- _foo() <-- foo().

Convert all internal libc usage of: aio_suspend(), close(), fsync(), msync(),
nanosleep(), open(), fcntl(), read(), and write() to _foo() instead of foo().

Remove all internal libc usage of: creat(), pause(), sleep(), system(),
tcdrain(), wait(), and waitpid().

Make thread cancellation fully POSIX-compliant.

5f02be00bc While comparing this with OpenBSD (ie: trying to figure out what mkstemps()
is good for... :-)), I discovered that part of the change when mkstemps()
was brought in was missed - it was missing the termination case to make
sure it doesn't walk into the suffix.  This isn't the same code OpenBSD
has, I think this is a little better as we terminate the loop in a better
spot.
