option (try to break at word bounaries) for SUSv3 conformance.
Partially based on the NetBSD version, with the following changes:
- style(9)
- break on <blank>s, not spaces, per POSIX (and GNU)
- when looking for last space on line, search backwards instead of
forwards; less comparisons needed this way.
- use LINE_MAX macro instead of a magic number and a comment saying it is
LINE_MAX.

due to conditions that suggest the possible need for stack growth.
This has two beneficial effects: (1) we can
now remove calls to vm_map_growstack() from the MD trap handlers and (2)
simple page faults are faster because we no longer unnecessarily perform
vm_map_growstack() on every page fault.
o Remove vm_map_growstack() from the i386's trap_pfault().
o Remove the acquisition and release of Giant from i386's trap_pfault().
(vm_fault() still acquires it.)
- get rid of the 4th level headings
- seperate the actions required to prepare the installation (getting
the CD, settings up the various daemons, ...) from the actual
installation
Translation teams: This patch moves some paragraphs around and changes
a lot of <sectX> headers, but does not contain any content changes in
the strict sense of the word (i.e. I did not rewrite paragraphs yet).
There were no changes to the indentation, either.

to use ``.if defined()'' inside bsd.own.mk to test for defines
in individual makefiles. For example, setting DEBUG_FLAGS in
Makefile didn't take the desired effect on the STRIP assignment.
Added bsd.init.mk (like in NetBSD) that handles the inclusion
of ../Makefile.inc and bsd.own.mk from all bsd.*.mk files that
"build something".
Back out bsd.own.mk,v 1.15: moved OBJFORMAT initialization back
to sys.mk (several source tree makefiles want to check it early)
and removed MACHINE_ARCH initialization (it's hard to see from
looking at the commitlogs what the problem was at the time, but
now it serves no purpose).
Prohibit the direct inclusion of bsd.man.mk and bsd.libnames.mk.
Protect bsd.obj.mk from repetitive inclusion. Prohibiting the
direct inclusion of bsd.obj.mk might be a good idea too.
environment needed at boot time to a dynamic subsystem when VM is
up. The dynamic kernel environment is protected by an sx lock.
This adds some new functions to manipulate the kernel environment :
freeenv(), setenv(), unsetenv() and testenv(). freeenv() has to be
called after every getenv() when you have finished using the string.
testenv() only tests if an environment variable is present, and
doesn't require a freeenv() call. setenv() and unsetenv() are self
explanatory.
The kenv(2) syscall exports these new functionalities to userland,
mainly for kenv(1).

statclock can access it in the tail end of statclock_process() at an
unfortunate time. This bit me several times on an SMP alpha (UP2000)
and the problem went away with this change. I'm not sure why it doesn't
break x86 as well. Maybe it's because the clocks are much faster
on alpha (HZ=1024 by default).
