018d9f6237 Remove the printf builtin command from sh(1), which command is not
used so often that it's worth keeping it as a builtin.

Now that all the printf invocations from within the system startup
scripts, we can safely remove it.

Urged by:	sheldonh  :)

No MFC is planned so far because it may break compatibility and
violate POLA.

d90c5c4ab4 Make test(1) a builtin command of our sh(1) for efficiency. The
binary size increase is 3,784 bytes (about 0.6%).

I don't drop the printf builtin while I'm here because some /etc/rc.*
scripts seem to use it before mounting /usr where printf(1) resides.

c4d9468ea0 mdoc(7) police:
Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text.
Not only this slows down the mdoc(7) processing significantly, but it also
has an undesired (in this case) effect of disabling hyphenation within the
entire enclosed block.

c644db6aa2 Improve shell documentation:
* Consistently misspell built-in as builtin.

* Add a builtin(1) manpage and create builtin(1) MLINKS for all shell
  builtin commands for which no standalone utility exists.  These MLINKS
  replace those that were created for csh(1).

* Add appropriate xrefs for builtin(1) to the csh(1) and sh(1) manpages,
  as well as to the manpages of standalone utilities which are supported
  as shell builtin commands in at least one of the shells. In such
  manpages, explain that similar functionality may be provided as a
  shell builtin command.

* Improve sh(1)'s description of the cd builtin command. Csh(1) already
  describes it adequately. Replace the cd(1) manpage with a builtin(1)
  MLINKS link.

* Clean up some mdoc problems: use Xr instead of literal "foo(n)"; use
  Ic instead of Xr for shell builtin commands.

* Undo English contractions.

c1c72a3c2a The immediate execution of traps I introduced in September 1998 (to
make /etc/rc interruptible in cases when programs hang with blocked
signals) isn't standard enough.

It is now switched off by default and a new switch -T enables it.

You should update /etc/rc to the version I'm about to commit in a few
minutes to keep it interruptible.

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..

7a2afe644c Implement the "ulimit" builtin. This is the analogon to csh's "limit"
command and badly needed in sh(1) for everybody who wants to modify
the system-wide limits from inside /etc/rc.

The options are similar to other system's implemantations of this
command, with the FreeBSD additions for -m (memoryuse) and -p (max
processes) that are not available on other systems.
