[RFC 00/34] Add initial support for NAN synchronized discovery

[Andrei Otcheretianski]

This patch series adds initial support for NAN synchronized discovery
by reusing the existing USD implemetation in wpa_supplicant.
This is based on the nl80211 kernel APIs proposed in RFC patch series
"[RFC v3 0/4] wifi: nl80211: Extend NAN APIs to allow more flexible
implementations", which introduces DW notification concept and allows
SDF transmissions over NAN device interface with proper timing.
This RFC patch series implements the following:
  - Add support for NAN device interface
  - Introduce NAN module, and refactor USD so it will be possible to
    reuse the existing implementation.
  - Handle DW notifications and support synchronized discovery
  - Extend NAN DE to support match, SRF and RSSI filtering.

In this implementation, NAN device interface can be used both for
synchronized and unsynchronized discovery (USD). For sync discovery, NAN
services (publish/subscribe) should be added with sync=1 parameter,
otherwise USD will be used. Sync discovery is only allowed after NAN
operation has been started.
