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

Add errc/verrc/warnc/vwarnc family: versions of err/... that take the errno
value to use for the strerror() message as an argument. Originally from
FreeBSD 3.0

Patch from Steffen Nurpmeso (sdaoden (at) gmail.com) with minor tweaks.

Remove historical comment about <varargs.h> and warn people from using
the _* functions outside libc

Adapt things to use __type_t instead of _BSD_TYPE_T_
Add new sys/_types.h header
Include machine/_types.h or sys/_types.h where applicable

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rescinded 22 July 1999.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

Part one of userland __P removal. Done with a simple regexp with some minor hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.

remove redundant __noreturn__ attributes now that __dead is sane for modern gcc

typo in comment

Expose protos for _{err,warn}{,x} regardless of __indr_reference being
defined since in the notdef __indr_reference case they are still present,
just as real functions. Fixes some alpha warnings.

use __x__ formats for __attribute__ arguments; guenther@gac.edu

Well, as we are heading for a release people are encouraged to rebuild their
entire trees for testing anyway, I might as well do this intrusive touching
of include files now. Added openBSD tags.
