FreeNAS Code

Mega commit to merge with internal repo, adds AD, LDAP, ssh keys in database, improves migrations, and much much more

Switch to patched py-ipaddr instead of patched django, add collectd to nanobsd build

Upgrade build to 8.2-beta1

Don't need this three times...

Remove packages that we have no GUI for, or any plans for a GUI in the base.

Move setting NANO_ARCH earlier so that FREENAS_ARCH will be the
default for all the things that it affects.

Eliminate unison while I'm here. It breaks cross building. We have
no plans for a gui and so far nobdoy has complained that it is
missing.

With these changes, I can now build a i386 cd on an amd64 host.

In post-south world order, we need to add --migreate

Finish up LAGG implementation, add south to the mix

use 40MiB for /var instead of 10MB. 10MB isn't enough for samba under load.

Implement Xin's proposed schema changes for LAGG:
* Create 3 LAGG Tables
+ Members Table
- device name
- options
+ Interface / Type Table
- interface (foreign key to Interfaces table)
- type (lagg protocol type)
+ Interface / Members Table
- Order Number (arbitrary integer)
- device (foreign key to LAGGMembers table)
- interface (foreign key to Interfaces table)
