- 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.

- Once we have shifted arguments thrice, base-bits-dir is $1 rather than $4.
Introduce $BASEBITSDIR for clarity and in order to avoid repeating this
mistake in the future. Fixing this ensures that we pick up the newly built
boot code and loader native to the target, which is especially relevant
when cross-building release images.
- It is pointless to specify an endianess for ISO 9660 images so strip that.

- 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].

Based on work by: gjb[1]
Discussed with: marius, nwhitehorn[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.

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.

Suggested by: many

Change yet another script to use /dev/mdX instead of /dev/mdXc (see
also r188438).

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.

Back out previous commit. Colin's fix to md makes the extra sleep
here unnecessary. Thanks Colin. :-)

Found another one. Why does mdconfig hate me? Add a "sleep 5" to
this script, without it sparc64 ISO building was consistently failing
because the /dev/md0 device name was not present when the commands
following mdconfig ran. Apparently there is the possibility of a delay
between when mdconfig finishes and the names become visible in /dev.
Yes, we could code this better than an unconditional call to "sleep 5"
but IMHO we should fix the underlying problem instead.

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.

Obtained from: share/examples/worm/makecdfs.sh

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.

- Use the correct boot/boot1 and boot/loader files.
- Use the newfs command similar to that in doFS.sh.

disklabel(8) is spelled bsdlabel(8) or sunlabel(8) these days.
Also make sure bsdlabel(8) (along with the disklabel(8) compat
link) still appear on the fixit floppies of platforms that use
it natively (alpha, i386, and pc98).
