When the driver (or most likely firmware) decides which AP to use
for roaming based on internal scan result processing, user space
needs to be notified of PMKSA caching candidates to allow RSN
pre-authentication to be used.

Introduce filtering for scheduled scans to reduce the number of
unnecessary results (which cause useless wake-ups).
Add a new nested attribute where sets of parameters to be matched can
be passed when starting a scheduled scan. Only scan results that
match any of the sets will be returned.
At this point, the set consists of a single parameter, an SSID. This
can be easily extended in the future to support more complex matches.

When the rssi of the current AP drops, both wpa_supplicant and the
firmware may do a background scan to find a better AP and try to
associate. Since firmware based roaming is faster, inform
wpa_supplicant to avoid roaming and let the firmware decide to
roam if necessary.
For fullmac drivers like ath6kl, it is just enough to provide the
ESSID and the firmware will decide on the BSSID. Since it is not
possible to do pre-auth during roaming for fullmac drivers, the
wpa_supplicant needs to completely disconnect with the old AP and
reconnect with the new AP. This consumes lot of time and it is
better to leave the roaming decision to the firmware.

In this implementation, a mesh gate is a root node with a certain bit
set in its RANN flags. The mpath to this root node is marked as a path
to a gate, and added to our list of known gates for this if_mesh. Once a
path discovery process fails, we forward the unresolved frames to a
known gate. Thanks to Luis Rodriguez for refactoring and bug fix help.

This patch updates the mesh peering frames to the format specified in
the recently ratified 802.11s standard. Several changes took place to
make this happen:
- Change RX path to handle new self-protected frames
- Add new Peering management IE
- Remove old Peer Link IE
- Remove old plink_action field in ieee80211_mgmt header
These changes by themselves would either break peering, or work by
coincidence, so squash them all into this patch.
