Subject: [PATCH] mac80211: split beacon retrieval functions
Split __ieee80211_beacon_get() into a separate function for AP mode
ieee80211_beacon_get_ap().
Also, move the code common to all modes (AP, adhoc and mesh) to
a separate function ieee80211_beacon_get_finish().

Subject: [PATCH] nl80211: MBSSID and EMA support in AP mode
Add new attributes to configure support for multiple BSSID
and advanced multi-BSSID advertisements (EMA) in AP mode.
- NL80211_ATTR_MBSSID_CONFIG used for per interface configuration.
- NL80211_ATTR_MBSSID_ELEMS used to MBSSID elements for beacons.
Memory for the elements is allocated dynamically. This change frees
the memory in existing functions which call nl80211_parse_beacon(),
a comment is added to indicate the new references to do the same.
