Fix incorrect range check for size in setvbuf

From enh AT google.com:

The existing test is wrong for LP64, where size_t has twice as many
relevant bits as int, not just one. (Found by inspection by
rprichard.)

Looks good to deraadt@ and millert@

Delete casts to off_t and size_t that are implied by assignments
or prototypes. Ditto for some of the char* and void* casts too.

verified no change to instructions on ILP32 (i386) and LP64 (amd64)
ok natano@ abluhm@ deraadt@ millert@

Add framework for resolving (pun intended) libc namespace issues, using
wrapper .h files and asm labels to let internal calls resolve directly and
not be overridable or use the PLT. Then, apply that framework to most of
the functions in stdio.h, string.h, err.h, and wchar.h. Delete the
should-have-been-hidden-all-along _v?(err|warn)[cx]? symbols while here.

tests clean on i386, amd64, sparc64, powerpc, and mips64

Remove unnecessary calls to __atexit_register_cleanup(), calling __sinit()
instead where necessary.

Fix the handle locking in stdio to use flockfile/funlockfile
internally when and where required. Macros in <stdio.h> are updated
to automatically call the underlying functions when the process is
threaded to obtain the necessary locking. A private mutex is added
to protect __sglue, the internal list of FILE handles, and another
to protect the one-time initialization. Some routines in libc that
use getc() change to use getc_unlocked() as they're either protected
by their own lock or aren't thread-safe routines anyway.

committing on behalf of and okay guenther@ now that we have install
media space available.

Back out previous commit, as it caused too much growth for the install
media to fit

ok kurt@, earlier version tested by sthen@ and jj@

zap remaining rcsid.

Kill old files that are no longer compiled.

okay theo

next citrus step.

libc+libstdc++ bump

deregister + ansify, no change in object code. ok deraadt@ millert@

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

Move __cleanup into mprotect'ed page to prevent unintentional modifications
similar to the atexit handlers. Idea and help deraadt@, ok deraadt@

a first pass at -Wall

Fix RCS ids
Make sure everything uses {SYS,}LIBC_SCCS properly
