• Fixup stray dots('...') on bootup and add some comments since we do loading of the filters twice during bootup?!
• Merge all interface related bootstraps under interfaces_configure so this allows us to handle propperly assigned bridge/gre/gif/.. devices that might are initialized later than assigned interfaces....

• Remove the wan word from most of the functions in this file.
• Remove the 's' from functions that deal only with one interface.
• Some other fixes in general.

Remove uneeded and commented out code.

Correctly return gre/gif addresses if selected on the firewall rules or needed elsewhere.

Oops, typo. Thanks, http://forum.pfsense.org/index.php/topic,11442.0.html

Make sure the /var/db/racoon path exists before starting racoon. This is
needed to ensure racoonctl can communicate properly with racoon.

Do not execute the command if interface is not configured at all(type = none).

• Array checks too.
• Add some style(9)

NOTE: Maybe someone needs to verify these strange checks on this function!

Add validation for the ca configuration array presence. Minor style fixes.
