MFC r245347: Add color.4th.
MFC r253919: Fix the bootable CD.

MFC r245177,r245346,r246283,r251650:

- Set WITHOUT_SVN=yes for textproc/docproj.
- Add CHECKSUM.* support in Makefile.
- Use ln -fs to create a symlink.
- Remove pkgadd for docports.
- Use WITHOUT_JADETEX=yes instead of WITH_JADETEX=no.
- Add {WORLD,KERNEL}_FLAGS to [BTWK]MAKE.
- Use makefs(8) and gpart(8) for sparc64 ISO image.
- Add publisher option to makefs(8).
- Add missing copyright notice.
- ISO 9660 specification allows only "d-characters" and "a-characters"
in the Volume Descriptor (section 7.4). In short, uppercase
alphanumeric + some symbols only. While the makefs utility automatically
converts the characters, $LABEL should be consistent in the scripts.

These fix a specification violation in 9.X iso9660 images, and cdrtools
dependency and endianness issue for sparc64 release media. The label is
now in uppercase letters only in all platforms.

MFC rev. 227283:
Add check-password.4th and screen.4th to the boot image. They are
needed by the loader.

Don't clobber the hosts /etc/fstab. $1 is empty at this point.

Fix ia64 ISO creation:
o boot/mfsroot.gz is no more. Copy it only when it exists so as still
to be compatible with Makefile.sysinstall.
o while here, make ispfw.ko optional as well.
o '-b bootimage' is not a valid argument for makefs. What was meant
was '-o bootimage'.
o create the boot image in the current directory so that makefs can
find the file. Previously it had to be created under $BASE because
that's how mkisofs wanted it.

Convert IA64 ISO script to use makefs instead of mkisofs.

Use labels to find release media instead of hard-coded device paths. This
makes booting more reliable (and working at all on USB sticks). While here,
move responsibility for setting up fstab into the various platform mk-*.sh
scripts.

The EFI system partition used to make the CD image bootable is running
out of space. Bump it up...

Increase the size of the EFI system partition from 16M to 20M.
We just ran out of space...

The current version of mkisofs is warning us that the -P option will
be changing with the next version, and we should be using -publisher
instead.

Put the ispfw.ko module on the EFI boot partition when creating a
bootable ISO. HP machines (like the rx2600) that (also) have isp(4)
may have a non-standard firmware on the controller. Our isp(4) driver
is not able to work with those and even panics. This makes installing
FreeBSD rather impossible. By adding the ispfw.ko module, we give the
user a chance to upload a certified firmware onto the card and so make
it possible to either use the isp(4) successfully or otherwise avoid
the panic.

Favor building the cdrtools port over fetching the package. There
hasn't been any package build for ia64 for a long time and in this
case it means that the cdrtools package on the FTP sites is one that
doesn't have mkisofs. This breaks the release build. By trying to
build the port first, we protect ourselves a bit more against this.

Add a publisher variable with the URL for the FreeBSD Project, and put
this into the ISO headers by specifying the -P option to mkisofs.

Set BATCH=yes to avoid bumping into interactivity in the port builds.

XXX /usr/ports is still hardcoded, should be ${PORTSDIR}

mkisofs(8) is now installed by sysutils/cdrtools.

This will be instantly MFC'ed.

- Removed vestiges of the IA64 boot floppy support.
- Fixed the bootable CD-ROM support for IA64.

Make IA64 a second port that comes with NO_FLOPPIES.

Double the size of the EFI boot image. 5MB is not enough. The kernel
is not compressed.

Make bootable ISO images by either 1) extacting the EFI partition
we created for the boot floppy, or 2) construct an EFI partition
by copying bits from /boot. The first approach creates a bootable
CD image that loads a memory disk and starts sysinstall, the second
approach creates a generic bootable CD.

Shamelessly copy the files over from the sparc64 port. Since there
was no history to speak of, a repocopy would not have bought us
anything. Versions copied:
