In theory, this should not really be needed, but Windows 7 uses
Registrar mode to probe AP's WPS capabilities before trying to use
Enrollee and fails if the AP does not allow that probing to happen.
This allows the AP to start as an Enrollee and send M1, but refuse
to continue beyond that (M3 will not be sent if AP PIN is not known).
Call ieee802_11_set_beacon() in addition to set_ap_wps_ie() when
processing WPS IE updates. This is needed with drivers that use
set_beacon() instead of set_ap_wps_ie() (i.e., nl80211).
Doxygen and some build tools may get a bit confused about same file
name being used in different directories. Clean this up a bit by
renaming some of the duplicated file names in src/ap.
