Hello,

We now have the infrastructure to report beacons/PANs, we also have the
capability to transmit MLME commands synchronously. It is time to use
these to implement a proper scan implementation.

There are a few side-changes which are necessary for the soft MAC scan
implementation to compile/work, but nothing big. The two main changes
are:
* The introduction of a user API for managing scans.
* The soft MAC implementation of a scan.

In all the past, current and future submissions, David and Romuald from
Qorvo are credited in various ways (main author, co-author,
suggested-by) depending of the amount of rework that was involved on
each patch, reflecting as much as possible the open-source guidelines we
follow in the kernel. All this effort is made possible thanks to Qorvo
Inc which is pushing towards a featureful upstream WPAN support.

Example of output:

	# iwpan monitor
	coord1 (phy #1): scan started
	coord1 (phy #1): beacon received: PAN 0xabcd, addr 0xb2bcc36ac5570abe
	coord1 (phy #1): scan finished
	coord1 (phy #1): scan started
	coord1 (phy #1): scan aborted

Cheers,
Miquèl

Changes in v3:
* Fixed most checkpatch.pl issues. A few remain to keep the visual
  consistent with the existing code (in the trace.h files).
* Added Alexander's Acked-by on each patch.

Changes in v2:
* Different way to forward the reason why a scan was terminated, instead
  of providing two different "commands" we provide the same "scan done"
  command and aside an attribute, saying whether the scan was aborted by
  the user or terminated by itself at the end of the required list of
  (complex) channels to scan.
