- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

- Add CHECKSUM.* support in Makefile[1].
- 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[2].
- Add publisher option to makefs(8)[2].

ISO 9660 specification allows only "d-characters" and "a-characters" in the
Volume Descriptor (section 7.4). In short, upper-case alphanumeric + some
symbols only. While the makefs utility automatically converts the characters,
$LABEL should be consistent in the scripts.

Garbage collect some unused variables and stray debug code.

Repair release CD generation on PC98 and sun4v after release building
changes, and backport the new logic (ISO images are TARGET dependant, not
TARGET_CPUARCH dependant) to Makefile.sysinstall. While modifying ISO
image scripts, change several archs to use makefs (from base) instead of
mkisofs (from ports) which makes release CD generation both faster and
self-hosting.

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 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.

Also warned by: trhodes
MFC after: 1 week

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.

Switch to using cdboot for booting i386 CD's by default.

Providing long filename support on the Macintosh requires over 30
megabytes of additional space on the install CD. Given our premium
for space, I don't think this is a wise use of 30MB. HFS support was
not provided on the FreeBSD 4.4 CDs and I received a grand total of 0
complaints.

Previous change to try to build `mkisofs' was
Submmitted by: dirk

Try to build `mkisofs' first, and only `pkg_add -r' if you cannot.

Fix my backwards logic.

+ do not hard code where a port may be installed to
+ uses `mkisofs' rather than `mkhybrid' as the new mkisofs is the merger
of the two
+ checks for `setcdboot's existsance and tries to pkg_add it if needed
+ removes English contraction

Add scripts and Makefile support for building ISO images automatically
as part of the release if MAKE_ISOS is set. Will also build the
first CD with packages (in addition to the "minimal" CD) if CD_EXTRA_BITS
points to them. This probably need a bit more work to get fully useful,
but it at least covers the basics for now.
