Hello,

This series follows the work done in the Linux kernel stack: now that
the core knows about the different netlink commands and attributes in
order to support passive scan requests from end-to-end, here are the
userspace changes to be able to use it.

Here is a list of the new available features.

* Sending (or stopping) beacons. Intervals ranging from 0 to 14 are
  valid for passively sending beacons at regular intervals. An interval
  of 15 would request the core to answer to received BEACON_REQ.
  # iwpan dev wpan0 beacons send interval 2 # send BEACON at a fixed rate
  # iwpan dev wpan0 beacons send interval 15 # answer BEACON_REQ only
  # iwpan dev wpan0 beacons stop # apply to both cases

* Scanning all the channels or only a subset:
  # iwpan dev wpan1 scan type passive duration 3 # will not trigger BEACON_REQ
  # iwpan dev wpan1 scan type active duration 3 # will trigger BEACON_REQ

* If a beacon is received during this operation the internal PAN list is
  updated and can be dumped or flushed with:
  # iwpan dev wpan1 pans dump
  PAN 0xffff (on wpan1)
	coordinator 0x2efefdd4cdbf9330
	page 0
	channel 13
	superframe spec. 0xcf22
	LQI 0
	seen 7156ms ago
  # iwpan dev wpan1 pans flush
  # iwpan dev wpan1 set max_pan_entries 100
  # iwpan dev wpan1 set pans_expiration 3600

* It is also possible to monitor the events with:
  # iwpan event

* As well as triggering a non blocking scan:
  # iwpan dev wpan1 scan trigger type passive duration 3
  # iwpan dev wpan1 scan done
  # iwpan dev wpan1 scan abort

Cheers,
Miquèl

Changes in v2:
* Dropped the binaries added by accident.
* New sync of the headers with Linux.
* Added two new commands to configure the stack regarding the number of
  PANs listed and their delay before expiration.
