Assume LAN unless we only have one interface and that is WAN.
If LAN is not there, no problem: the text will either show
WAN if it works or show LAN and do nothing.

We could argue that 1 interface that is not WAN or LAN is
possible and should receive anti-lockout too, but this would
change the previous behaviour too much and is not generally
possible from the GUI or console.

(mvc) fix mangled dropdown boxes on some inputs, reset all form_input_tr items to avoid further strangeness..

Don't need this, it was a comaptibility test.  The gained
flexibility from -D is far more important.

This reverts commit dfb09411.

This finally repairs ssh key login.  :)

(volt, macro usage) revert macro change, it looks like this really was a bug in PHP7/Phalcon, looks solved now. closes https://github.com/opnsense/core/issues/1245

(pam) switch normal console to pam, because we lock accounts locally now, console login should be switched at the same time

(pam) work in progress: pam helper skip for non local users, for non existing users pam should proceed to the next option.

When our pam modules is used, we set local auth to disabled (locked) for our users, non local users should automatically use normal unix auth.
For this to work, we should pass PAM_USER_UNKNOWN as return value in our pam module when the user is not local to us and unauthenticated.
