FreeNAS Code

fix bug on replace in-place (wrong pool name)

use zpool id to import

Don't automatically chown unknown mountpoints to root:wheel in the event
the user/group cannot be resolved on the FreeNAS box.

This can create undesirable side effects (in particular with NFS) if the
FreeNAS and client instance user/group list are out of synch and someone
logged into the box and changed the user/group to an 'unknown'
user/group (chown(2) allows numeric assignment anyhow -- for better or for
worse -- and chown(1) allows numeric / name based assignment).

This should be handled via Exceptions in the future, but for now
defaulting to root:wheel in the GUI alone is good enough.

Document the behavior accordingly.

1. Drop unnecessary 'r' open mode flags.
2. Use ContextSuites instead of ad hoc open->read/write->close.

Style changes.

Fix the config uploading logic. It worked over
one migration, but it had issues sticking with
the next set of schema, so there's most likely
more changes incoming in the near future to
this functionality.

Revert on fail functionality with a broken DB
appears to be completely broken >_>.

Grab correct user and group from stat info.

Restore pw assignment dropped in r7422.

Don't pull connect info from the database as it's already done in the ldap objects.
