Replace the prototype vaps_<ifn> and vap_create_<ifn> variables with

Browse Source 
more wlans_<ifn> and create_args_<ifn>

Add documentation for these variants and generally update the wireless
device example.

There is are very short lived shim from vaps_<ifn> which produces
a warning and vap_create_<ifn> which does not.  Misuse the MFC
notification service to remind me to remove them.
