Rework how we layout the CD/DVD ISO images for releases. Note that this

is only the first stage and does not yet handle packages (which will move
to their own disc(s)).
- By default, include the live filesystem on disc1, so that disc1 is now
  both an install disc and a fixit disc.  The images can still be split
  into two separate discs by specifying SEPARATE_LIVEFS=yes.
- Remove /usr/ports from the live filesystem disc as the merged images
  do not fit on even i386 otherwise.  Also, the merged image already
  contains a tarball of the entire ports tree, so /usr/ports was a
  duplicate anyway.
- Stop building port READMES for the release sinc they are no longer used
  (/usr/ports in the live filesystem was the last remaining user).
- Split cdrom.1 into three targets.  cdrom.1 builds the live filesystem
  image.  cdrom.2 builds the disc1 image.  Note that if SEPARATE_LIVEFS
  is not specified these both write to the same area.  cdrom.3 builds
  the bootonly image and the UFS miniroot.
- The various distribution directories are now in a <buildname>
  subdirectory of disc1 rather than being in the root so that the merged
  image's root is not quite as cluttered.
- The disc1 image is now called disc1.iso and we no longer build a
  miniinst.iso image.  If CD_EXTRA_BITS is defined, then the iso.1 target
  will simply include those bits in the disc1 image that it builds.
