Fix calls to ipsec_enabled() added in 179ab6b364

Eliminate a few more cases of $config['ipsec']['enable'].

Mostly when dealing with enc0 interface.

Catch one more possibility for the IPSEC interface name, this match the code used in other places.

Add a new function that returns the current state of IPSEC.

Whenever we have phase1 entries, IPSEC is considered enabled.

etc inc delete $Id comments

and bits of white space.
Note: There are plenty of files still with old-format copyright sections
in here.

unbound_statistics section should be written to unbound.conf

The stuff generated by unbound_statistics() goes into unbound.conf
It had got separated out and was going nowhere. This puts the behavior back the way it was yesterday.

Note: There is a separate issue about this because the UI has no place to actually select the statistics settings. There is some upgrade code that looks like it was converting statistics settings from the old Unbound package into custom commands in the integrated Unbound. So it looks like the unbound_statistics() function can/should be removed???

Add global so that unbound.conf gets written

to the correct place based on $g setting.
