FreeNAS Code

WIP, committing progress.

Remove some debugging statements and add additional checks for data returned from the database.

Forgot to import pbi_delete.

Delete pbi method added, modified pbi install method to use new pbi fields.

Revert r9154.

There are a number of issues that can result from one setting the netbios, service names from DNS. DNS is less limiting than netbios (15 character limit) in terms of length, and Windows does some tricky things if a netbios name has already been taken on the network, but it turns out that NetBIOS permits some characters not allowed in the DNS spec (!, $, etc). See http://support.microsoft.com/kb/909264 for more details.

This also (according to jhixson), breaks the AD tie-in because it uses the netbios [database?] field somewhere in the code.

Rename that I let slip at some point.

Set name from the PBI.

Raise a MiddlewareError if a pbi installation fails.

Add an API for determining whether or not a module has been loaded (notifier.kern_module_is_loaded).

This will allow people to create volumes, regardless of whether or not zfs.ko has been preloaded.

Please read the docstring for more details.

Do-Not-Merge: I need to fix the hack in the iX tree.

Fix path.
