Subject: Multiple changes stacked as one commit since they all depend on one
 another.

First, change sysinstall and the Makefile rules to not build the kernel
nlist directly into sysinstall now.  Instead, spit it out as an ascii
file in /stand and parse it from sysinstall later.  This solves the chicken-n-
egg problem of building sysinstall into the fsimage before BOOTMFS is built
and can have its symbols extracted.  Now we generate the symbol file in
release.8.

Second, add Poul-Henning's USERCONFIG_BOOT changes.  These have two
effects:

	1. Userconfig is always entered, rather than only after a -c
	   (don't scream yet, it's not as bad as it sounds).

	2. Userconfig reads a message string which can optionally be
	   written just past the boot blocks.  This string "preloads"
	   the userconfig input buffer and is parsed as user input.
	   If the first command is not "USERCONFIG", userconfig will
	   treat this as an implied "quit" (which is why you don't need
	   to scream - you never even know you went through userconfig
	   and back out again if you don't specifically ask for it),
	   otherwise it will read and execute the following commands
	   until a "quit" is seen or the end is reached, in which case
	   the normal userconfig command prompt will then be presented.

  How to create your own startup sequences, using any boot.flp image
from the next snap forward (not yet, but soon):

	% dd of=/dev/rfd0 seek=1 bs=512 count=1 conv=sync <<WAKKA_WAKKA_DOO
USERCONFIG
irq ed0 10
iomem ed0 0xcc000
disable ed1
quit
WAKKA_WAKKA_DOO


Third, add an intro screen to UserConfig so that users aren't just thrown
into this strange screen if userconfig is auto-launched.  The default
boot.flp startup sequence is now, in fact, this:

	USERCONFIG
	intro
	visual

(Since visual never returns, we don't need a following "quit").
