9dee16dba6 Fix handling of SIGINT/SIGQUIT for foreground subprocesses. Most
urgent need is when you run sh around a program that intentionally
uses SIGQUIT/SIGINT for asynchronous events, i.e. $EDITOR started from
system(2), like many mailers do. This fixes PR bin/1206 and possibly
bin/4241.

The solution committed has been tested for a large number of possible
cases (see recent discussion on cvs-committers). I completed a make
world, made sure 'make world' is interruptable and used the changed
/bin/sh as a login shell all day, including job control and using
SIGQUIT-catching programs (to write this message :-).

Reorder includes to be alphabetical some places since I already was in
here.

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.

4417f6297d Fix for PR#1287. This makes sh behave sensibly in case statements in the
face of aliases.  Note, bash doesn't do aliases while running scripts, but
"real" ksh does..

Also:
  Reduce redundant .Nm macros in (unused) bltin/echo.1
  nuke error2, it's hardly used.
  More -Wall cleanups
  dont do certain history operations if NO_HISTORY defined
  handle quad_t's from resource limits

16992ff483 Misc cleanups and fixes from Bruce:
- don't put \n on error() calls, error adds it already.
 - don't prepend "ulimit" on error() calls in miscbltin.c.
 - getopt typo on ulimit -p -> -u conversion
 - get/setrlimit() calls were not being error checked

ulimit formatting cleanup from me, use same wording as bash on Bruce's
suggestion.  Add ulimit arg to output on Joerg's suggestion.

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..
