- 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.

Clarify/extend in several places and make sure that everything matches reality.

Add mkuzip(8), non-GPL utility to compress filesystem images for use with
geom_uzip module. This is based on utility I wrote some 3 years ago for a
hack for md(4), which functionally was close to what geom_uzip does today.

Since I don't have a time to test that it compiles/works on other arches,
stick it to i386 only. Will do it later.

Unlike original cloop util, this one embedds FreeBSD-compatible shell code
into the generated image, not Linux one. Unfortunately severe space
restriction imposed by the CLOOP format doesn't allow to put conditional
code which will work both on Linux and FreeBSD. In fact it was quite a
challenge to fit necessary FreeBSD code into 127 bytes. ;-)
