[PATCH v2 00/35] Add initial support for NAN synchronized discovery

[Andrei Otcheretianski]

This patch series add initial support for NAN synchronized discovery
by reusing the existing USD implemetation in wpa_supplicant.
This is based on the latest wireless-next tree, which introduced
DW notification concept and allows SDF transmissions over NAN device
interface with proper timing.
This patch series implement 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.
  - Testing coverage
 
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.
 
Changes in V2:
- Fixed sync follow up addressing and added follow up hwsim test
- Fixed NAN cluster ID configuration.
- Increased timeouts in hwsim tests for discovery events.
- Don't set FSD bit in sync discovery tests.
