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.

929273386f Add three-tier symbol naming in support of POSIX thread cancellation
points.  For library functions, the pattern is __sleep() <--
_libc_sleep() <-- sleep().  The arrows represent weak aliases.  For
system calls, the pattern is _read() <-- _libc_read() <-- read().

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.

6a8e2895aa asprintf() does use realloc() internally, but saying so in the manpage can be
misinterpreted to mean that the pointer passed to asprintf() must be suitable
for passing to realloc() as-is (ie. either a NULL pointer or a valid pointer).

fbc400a67a Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

     .\"    $Id$
     .\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

b300c1d8f9 The pseudocode in the synopsis didn't come close to actually
compiling, since <stdio.h> correctly doesn't declare off_t although
the pseudo-prototypes for the new fseeko() and ftello() functions

versus the vprintf() family.

e8420087b0 Replace memory leaking instances of realloc with non-leaking reallocf.
In some cases replace if (a == null) a = malloc(x); else a =
realloc(a, x); with simple reallocf(a, x).  Per ANSI-C, this is
guaranteed to be the same thing.

I've been running these on my system here w/o ill effects for some
time.  However, the CTM-express is at part 6 of 34 for the CAM
changes, so I've not been able to do a build world with the CAM in the
tree with these changes.  Shouldn't impact anything, but...

64a965e707 Replace my original asprintf() and vasprintf() hacks with something
more cleanly integrated with stdio.  This should be faster and cleaner
since it doesn't memcpy() the data into a seperate buffer.  This lets
stdio allocate and manage the buffer and then hand it over to the user.

4fea76f539 Fix a nasty flaw as a result of using the arc4random() pre-seeding of
leading XXX's.  It could wrap an uppercase character through chars
like:  [ \ ] ^ _ `  in between Z and a.  The backslash and back tick
might be particularly nasty in a shell script context.  Also, since
we've been using upper-case generated values for a while now, go with
the flow and use them in the pathname search rotation.

ec216c2634 Add FILE locking stubs for libc.
Change the FILE locking to support kernel threads when linked with
libpthread (which you haven't see yet). This requires that libc become
thread-safe and thread-aware, testing __isthreaded before attempting
to do lock/unlock calls. The impact on non-threaded programs is minor.
This change works with libc_r, so it's the best compromise.
