FreeNAS Code

- Consolidate create_cache_filesystem into rc.freenas and simplify the logic a bit.
- Boost the cache filesystem requirements up to 2.0GB to deal with the fact that AD caching sucks up a lot of memory to cache large AD forests. This doesn't solve everything, but it helps at least (I wish the ad cachefill logic streamed through data a bit more gracefully and the winbind cache didn't eat up so much memory, but we'll improve this in the future..).

Jail stuff.

Apply the super secret delphij method to remove /tmp in the event that it has stuff in it (in particular if someone setup the core dump format string to point to somewhere in /tmp.. hehe).

Add the means to specify the interface the jail should use.

Fix whacky shell syntax that wouldn't work if I did

foo()() {

}

but for some weird reason works with

foo()()
{

}

Comitting some plugins/pbi stuff, more to come.

lets avoid the use of django data structures in order to use python built-in (SortedDict vs OrderedDict)

this dojango dojo app is legacy and never has been used!

i18n tag is now built-in, we don't need to load it

attrs_dict makes no sense in services.forms
