'RELENG_2_2_5_RELEASE'.

This commit was manufactured to restore the state of the 2.2.5-RELEASE image.
Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs.

	- Add the .PHONY, .PARALLEL, and .WAIT directives
	- Added the -B and -m commandline flags
	- misc. man page cleanups
	- numerous job-related enhancements
	- removed unused header file (bit.h)
	- add util.c for functions not found in other envs.
	- and a few coordinated whitespace changes

FreeBSD now only contains sccsid-related diffs. :)

$(.CURDIR}/obj search while retaining compatability of new
prefix with cwd for the current source tree builds.
.TARGETOBJDIR has been removed from make and CANONICALOBJDIR set in
bsd.obj.mk

The builtin object directory searching is defined specifically as:

If MAKEOBJDIRPREFIX is defined, the search order is
${MAKEOBJDIRPREFIX}${.CURDIR}
${.CURDIR}

Else if MAKEOBJDIR is defined, the search order is
${MAKEOBJDIR}
${.CURDIR}

Otherwise, default to the search order
${.CURDIR}/obj.`uname -m`
$(.CURDIR}/obj
/usr/obj${.CURDIR}
${.CURDIR}

really want them) from /usr/src.  This is the final version of the
patches, incorporating the feedback I've received from -current.

problems in the process:

1. Quoting should work properly now.  In particular, Chet's reported bash
   make problem has gone away.
2. A lot of memory that just wasn't being free'd after use is now freed.
   This should cause make to take up a LOT less memory when dealing with
   archive targets.
3. Give proper credit to Adam de Boor in a number of files.
