FreeNAS Code

Fix typo.

Modified pbi delete method to remove mountpoints associated with it (I thought foreign keys automatically cascaded deletes, I guess I misunderstood). Added method to remove the plugins jail as well, leaving debug syslog calls in for now, will remove once tested more thoroughly.

Check for disk serials before creating new Disk entries

Do-Not-Merge: This will be handled in another way

Fix logic on the sync_disk method

If the disk identifier is not found in the database check for the
disk name and update that entry instead of creating a new one.

Do-Not-Merge: Will be handled in another way later

Fix name of the raised exception in the docstring

(pointed out by gcooper)

Make sure to delete a static route using the masked version

Make sure to try to delete a static route from the routing table

TODO:
When a static route is entered it is placed in the database as-is.
So, if you enter 10.50.50.50/8 in reality it will be 10.0.0.0/8
and then fail to be deleted from GUI because the former is not
accept for route(8)

Remove references to jail_interface.

Rework the samba services to be executed independent of one another and also to honor rc.d better.

The rc.d script reworking was submitted per PR # ports/164010, s.t. we can
now manipulate the states of the individual samba services instead of having
to restart the entire lot and kill services manually (I modified the AD and
CIFS services to follow the new world order, but I didn't change the LDAP code
as I don't have the required infrastructure to test the change, yet). This
saves time when manipulating AD and CIFS now and reduces service interruption
(CIFS shares stay up and running when AD is turned off, and now AD can be on
without having CIFS enabled).

Bring back the rc.d changes for this branch.
