Log why we're writing a new config out

No need to use a reference to the array, if it doesn't exist already
this tends to make it exist the next time a write_config() occurs
which is now happening during bootup thanks to OpenVPN...yay! ;)

fix 4.6->4.7 upgrade check

Correct mode setting to correct permissions in octal mode

Remove unused and possibly erroneous code.

Merge lan configuration to the interfaces_wan.php page wich does the configuration of all
other assigned interfaces.

set auto channel properly

Use different names for pppoe and pptp fields so that problems reported by
http://forum.pfsense.org/index.php/topic,11220.0.html is fixed. Reflect the changes even
on config conversion part.

Add even some code in preparation of merging even lan on the same page.

Reflect the change on convert_friendly_interface_to_real... into get_real_wan_interface to return the real interface even for disabled ones. They are the same function that needs to be cleand up with the names in some distant future.

When restarting an OpenVPN process, don't send a term signal and expect it
to exit within a fixed time frame of two seconds. The old process may take
longer to exit and cause the new process creation to fail. Instead, check
the process status every 1/4 seconds and only continue once it terminates.
