sh: Fix duplicate prototypes for builtins.

Have mkbuiltins write the prototypes for the *cmd functions to builtins.h
instead of builtins.c and include builtins.h in more .c files instead of
duplicating prototypes for *cmd functions in other headers.

sh: Various warning fixes (from WARNS=6 NO_WERROR=1):
- const
- initializations to silence -Wuninitialized (it was safe anyway)
- remove nested extern declarations
- rename "index" locals to "idx"

Use -s to flag POSIX's "special built-in" utilities in builtins.def. Add a
new member to struct builtincmd and set it to 1 if -s was specified. This
is done because there are cases where special builtins must be treated
differently from other builtins.

Obtained from: NetBSD (builtins.def part)

Use prototypes in the generated builtins.{c,h} files.

/*- or .\"- or #- to begin license clauses.

Remove clause 3 from the UCB licenses.

Do not assume there is only a space between #define and the macro name
when grepping for JOBS. The recent style cleanup replaced the space with
a tab and broke job control detection. Little edits, disastrous consequences.

Avoid accidentally making "-h" a synonym for "fc".

Obtained from: NetBSD

Remove now-obsolete __STDC__ ifdefs, remove redundant NULL definition and
include stdlib.h for NULL.

Use secure temporary filenames during build.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Merge of 4.4-Lite2 sh source, plus some gcc -Wall cleaning. This is a
merge of parallel duplicate work by Steve Price and myself. :-]

There are some changes to the build that are my fault... mkinit.c was
trying (poorly) to duplicate some of the work that make(1) is designed to
do. The Makefile hackery is my fault too, the depend list was incomplete
because of some explicit OBJS+= entries, so mkdep wasn't picking up their
source file #includes.

This closes a pile of /bin/sh PR's, but not all of them..

Bring in my changes for removing the pestilent obj links (unless you
really want them) from /usr/src. This is the final version of the
patches, incorporating the feedback I've received from -current.

Make build work, even if there is no obj subdir.
