FreeNAS Code

This slipped. Oops.

Looks like I needed __system_nolog instead of __system... much grief over this one.

Rename to plugins_jail to ease confusion in my own mind.

1. Create variables for cd-upgrade and need-update so that scripts can refer to the variables if need be from within rc.freenas; this also makes the variable names easier to search for when looking for affected sections of code.
2. Fix the fact that failed CD based upgrades were in fact broken due to the fact that install.sh created the file as cd_update and ix-update expected for there to be a file named cd_upgrade. Favor the filename cd-upgrade because this is consistent with what's being used with need-update as it uses a dash instead of an underscore, and also because semantically cd *upgrade* reflects the operation being performed better than cd *update* does.

Oops, increment port.

Dump pbi info into the database when installing

Hack in fixes for simple GUI driven cases that have been broken with AD for a long time (clock skew with PDC, domain realm join failures, etc) because I'm tired of the fact that I have to repeat myself over the phone so many times with customers and that I have to handhold people in order to ensure that they're install works when in reality the software itself was broken.

Also, call forcestop on ix-activedirectory and ix-kinit so it actually unjoins from the domain and deletes the Kerberos tickets because it was always assuming that it was in start state as opposed to stopping state.

This fixes the high ticket items that have been pissing me off for a long time with our middleware. Now, to fix the other brokenness at boot... but first... sleep...

More pbi stuff to play with.

Ability to upload/install PBI files into a jail added.
