fbbd9655e5 Renumber copyright clause 4
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

454a02b372 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.

6262b84eee sh: Import arithmetic expression code from dash.
New features:
* proper lazy evaluation of || and &&
* ?: ternary operator
* executable is considerably smaller (8K on i386) because lex and yacc are
  no longer used

Differences from dash:
* arith_t instead of intmax_t
* imaxdiv() not used
* unset or null variables default to 0
* let/exp builtin (undocumented, will probably be removed later)

Obtained from:	dash

2cac6e364a sh: Constify various strings.
Most of this is adding const keywords, but setvar() in var.c had to be
changed somewhat more.

39376f45e2 - Fix bugs where the value of arithmetic expansion$((...)) was trucated
to type int.
- Change the type used for arithmetic expansion to intmax_t (ie. 64 bit on all
  currently supported FreeBSD architectures).  SUSv3 requires at least type
  long but allows for larger types.  Other shells (eg. bash, zsh, NetBSD's sh)
  do that too.

1130b656e5 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.

aa9caaf657 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..

069428af6d Import the 4.4BSD-Lite2 /bin/sh sources
Requested by: joerg

(Note, this is mostly going to be conflicts, which is expected.  Our entire
 sh source has a mainline, so this should not change anything except for
 a few new files appearing.  I dont think they are a problem)
