pfSense

Add code to allow applications on pfSense itself that bind to a socket or want to source route traffic to work. This fixes DynDns on multi-wan as the simplest of it.

Add a timeout for curl_exec. Combine all dyndns.org methods to one catching up with its API changes.

Fix regex on matching ip when behind nat.

Move checking if dyndns is enabled to the proper place.

Actually disable flowtables support by default.

Perform more strict validation on CA and Cert names before proceeding in the wizard.

Simplify "isset($rule['l7container']) and ..." as its already evaluated
above and sets $l7present.

Make PPP redial when the connection is dropped. Also, fix PPP uptime display.

Remove unnecessary variables.

Implement reporting and logging of historical PPP uptime with data persistent through reboot.

Also, change the way uptime is captured. The mpd console is no longer used to
get PPP uptime data, which will prevent spamming of PPP logs with console access messages....
