- 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.

Start teaching pc-sysinstall about IPv6.

Add some additional empty string checks for IPv4 and try to configure
a netmask along with the address rather than doing things twice.

Contrary to AUTO-DHCP, IPv6-SLAAC will accept static configuration
as well, which we will use at least for resolv.conf currently and
if we were given a static address configure that as an alias as well.

The pc-sysinstaller changes going along were committed to PC-BSD as r10773.

Bring in Kris Moore's pc-sysinstall shell script from PC-BSD. This
shell script is the back end logic necessary for an installer. It
contains both query routines to allow a front-end installer to present
reasonable choices to the user and also action routines which allow
the front end installer to put a FreeBSD distribution onto a disk. It
supports installing onto the usual suspects, as well as advanced
features like Mirroring, ZFS, Encryprion and GPT labels.

While this is only the back-end of the installer, it can do unattended
scripted installations. In PC-BSD's world view, all installations are
scripted and all the front-end does is write the script. As such, it
is useful in its own right.

This has been extensively tested over the past several releases of
PC-BSD. However, differences between that environment and FreeBSD
suggest there will be a period of shake-out while those differences
are discovered and corrected.

A text-based front-end is in the works. For the GUI-based front-end,
you can use the PC-BSD distribution.

Kris' BSDcan paper on pc-sysinstall is linked off his talk on the
BSDcan site:
http://www.bsdcan.org/2010/schedule/events/173.en.html

The man page is written by Josh Paetzel, and I wrote the Makefiles for
the FreeBSD integration. Kris wrote the rest.

This represents version r7010 in the PC-BSD repo.
