Vendor-specific IEs are supposed to be in the end of the frame, so move
WMM into the end of Beacon, Probe Response, and (Re)Association Response
frames. In addition, move HT IEs to be later in (Re)Association
Response to match the correct order.
hostapd_eid_wpa() adds multiple IEs and the end result may not always be
correct. If WPA is enabled, WPA IE (vendor-specific) gets added in the
middle of the frame and not in the end. This would require a larger
change to spliut the IEs from WPA module into separate locations when
constructing Beacon and Probe Response frames. This is not yet addressed.
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.
This code can be shared by both hostapd and wpa_supplicant and this
is an initial step in getting the generic code moved to be under the
src directories. Couple of generic files still remain under the
hostapd directory due to direct dependencies to files there. Once the
dependencies have been removed, they will also be moved to the src/ap
directory to allow wpa_supplicant to be built without requiring anything
from the hostapd directory.
