pfSense

Fixes #2364. On busy pppoe servers it might take some time before mpd exits. Check for this before trying to restart

Fixes #2209. Obey the mtu value set on the interfaces.php page. Though this value will be overwritten if there is a configuration under PPP settings tab. Maybe a good idea is to set MRU at the same value if not set?

If specified use the default settings for bw limitation rather than 0

Make file names match to make this work

Oops add forgotten global for config

If extra bw attributes are supplied during reauthentication apply and log them

Unlock if error occurs

Fixup ntpd logging

On its own, ntpd does not sync fast enough at bootup, so bring back the ntpdate sync but improve it so it can't get stuck forever.

Conflicts:

etc/rc.newwanipv6

Hackish workaround for ntpd failing to move away from init when called from within PHP 5.2, PHP 5.3 has a better workaround.
