b04b95ab47 Build a file "boot" which consists of boot1 and boot2 concatenated.
There is little if any reason to treat the two components separately
and it will simplify disklabel(8) and libdisk if we didn't.

8e6206d943 Fix interactive booting:
o Revision 1.38 introduced the -n flag.  It conflicted with the
  RB_BOOTINFO flag, so was in effect always on.  Change the -n flag to
  be bit 0x1c instead of 0x1f.  This also had the consequence that a mal-formed
  /boot.config would render the system unbootable because the user was
  unable to enter anything at all on the command line.
o Remove the initialization of opt to be RB_BOOTINFO since we filter that bit
  out and do not otherwise use it.

f62a945f30 RIP liloldr.
It is not complete (the LILO root= specification isn't passed to our
loader for instance), it has not been touched in over 2 years.  Linux has
moved on to GRUB, so this is OBE now.  If someone creeps up to work on it,
it could become a port.

2db4f48c6a Make both UFS1 and UFS2 fit on the same boot blocks. These are a
subset of Peter's patchs that are believed to be safe.

Makefile tweaks:
o -fomit-frame-pointer
o Change default to building both UFS1 and UFS2 bootblocks.

Lots of boot2 tweaks:
o lookup is only ever called with kname, so use it directly.
o inline memsize
o getstr are only ever called with cmd, so hardware that.
o tweaks to the parsing code to test after the conversion rather than
  before since we tested after anyways.
o eliminate support for %x in printf.
o eliminate a few bytes in printfs.
o Tweak the boot banner.
o eliminate support for wd and "  " devices (I might add wd back to
  keep bde happy).
o eliminate support for a few arguments.

This takes us from -162 bytes free to 67 bytes free.

I've tested this only on a few systems, so be careful when updating to
this change.

it possible to make UFS1_ONLY and UFS2_ONLY versions which fit inside the

3bb24c35f2 Split MBR and PC98 on-disk sliceformats out from disklabel.h, step 1:
Peter had repocopied sys/disklabel.h to sys/diskpc98.h and sys/diskmbr.h.

These two new copies are still intact copies of disklabel.h and
therefore protected by #ifndef _SYS_DISKLABEL_H_ so #including them
in programs which already include <sys.disklabel.h> is currently a
no-op.

This commit adds a number of such #includes.

Once I have verified that I have fixed all the places which need fixing,
I will commit the updated versions of the three #include files.

66422f5b7a Initiate deorbit burn for the i386-only a.out related support. Moves are
under way to move the remnants of the a.out toolchain to ports.  As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL.  It has already lasted WAY beyond
that.

Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.

401e7fff61 Revert previous untested revision. The i386 loader consists of three parts:
At the front is btxldr, in the middle is BTX itself (our mini-kernel), and
then the 'client' (loader.bin) which is the actual loader itself.  boot2
just executes a raw ELF or a.out binary with the only setup provided being
that a bootinfo structure is passed on the stack.  Now, since loader.bin
is a BTX client, the loader needs to be able to locate a BTX kernel for
the client to execute in the context.  Thus, just like pxelder, btxldr
uses the a.out header on the loader binary to find the BTX kernel stored
in the loader and set it up.  It does _not_ just reuse the BTX kernel
that boot2 invoked it with.  This is because it can't assume that it will
_have_ a "spare" BTX kernel lying around.  For example, when cdboot
loads the loader there isn't an existing BTX kernel.  In fact, cdboot
will only work with an a.out loader as well since it also "borrows" the
BTX kernel in the loader binary (which it finds by parsing the a.out
header) just as pxeldr does.  The only difference between cdboot and
pxeldr is where they get /boot/loader from.

If we wanted to make /boot/loader be an actual ELF binary we would need
to change the following utilites to handle that (and they all have to be
able to handle locating the BTX kernel inside of an ELF binary somehow):
- btxldr
- pxeldr
- cdboot

If we didn't want to require a flag day but make the transition smooth
then we need to be able to support both a.out and ELF versions of
/boot/loader which isn't exactly trivial since all three of these utilities
are written in assembly.
