  Log:
  Overhaul our boot floppy generation system so that it scales better and
  requires minimal care and feeding for future releases.
  - Consolidate multitude of floppy related constants down to a normal
    FLOPPY set for 1.44 floppies and on PC98 a SMALLFLOPPY set for 1.2
    floppies.  Also, cleanup the i386 arch section by not duplicating
    constants that are the same on both machine types (i386 and pc98).
  - Update the ZIPNSPLIT macro to generate a file chunks that will actually
    fit onto 1.44 floppies formatted with UFS1.  Unfortunately, split(1)
    seems to be somewhat buggy, so the files generated are slightly larger
    than the argument passed to split.
  - Split the release.10 target into 3 targers: floppies.1, floppies.2 and
    floppies.3 that are added to EXTRAS only if NOFLOPPIES is defined.
    floppies.1 builds the install floppies, floppies.2 builds the fixit
    floppy, and floppies.3 generates the md5 sums and READMEs for the
    floppies/ directory.
  - Drop the by now largely obsolete and less useful boot.flp picture.  This
    was more useful when the mfsroot lived inside the kernel rather than
    being loaded from a separate file by the loader.
  - Only build a single mfsroot containing no modules that is used for all
    installation methods.
  - Use split-file.sh to split up a gzipped GENERIC kernel into however many
    floppies it takes for the boot kernel.  Currently, a stock 5.2 GENERIC
    kernel including WITNESS, INVARIANTS, DDB, and other assorted bloat fits
    onto 2 additional floppies besides the boot floppy with some room to
    spare.
  - If SPLIT_MFSROOT is defined, the mfsroot.gz file is similar split into
    however many floppies are needed.  Currently it is not defined as the
    mfsroot.gz fits onto the current boot.flp with room to spare.
  - Add a 'makeFloppySet' target which builds a floppy set for a file that
    was split using split-file.sh.
  - Rename the doMFSKERN target to 'buildBootFloppy' as that more closely
    matches what it does now.  We no longer build a custom BOOTMFS kernel for
    each boot floppy.
  - We no longer build a 2.88 boot.flp image to use with emulated CD booting.
    The non-emulated cdboot works for almost everyone who boots off of CD and
    if it doesn't work on a particular machine, the user can always boot from
    the 1.44 floppy images.
  - We no longer build a driver floppy or stick kernel modules in the mfsroot
    since we now use a stock kernel when booting from floppy.
