Add NULL check to wireless functions.

The old interface_translate_type_to_real function used previously would return OPTX
if it was passed "OPTX" and OPTX existed but was unassigned, whereas get_real_interface returns NULL, so now we
check for NULL.

I think this is supposed to be get_real_interface too, not get_parent.

Revert if I mis-understood.

Change name of function "interface_translate_type_to_real" to match what it's doing (or should be doing.)

Next commits will change functionality of this function because before now
it's identical to "get_real_interface" function (because of bug mentioned below.)...

Resolves #1216. Do not create nat entries on ovpn interfaces.

Warn users a different way if packages are being reinstalled in the background. Only lock out package pages, still print a giant warning on the others. (Some people were getting stuck in this state http://forum.pfsense.org/index.php/topic,32531.0.html )

Actually send a notice even if no default queue could not be found. This might be serious in some cases.

Do not put the queue config on the rules if there is no default queue, just log it. This prevents errors in rules loading which is worse than having no shaper.

Log the errors we know for not allowing a queue to be added.

Add the npt tag which is used by the IPv6 tree to the 2.0 mainline tree.
This prevents a config blowup when a ipv6 config loads on 2.0.
