WiFi Protected Setup (WPS) update

The intent is to get this work merged into the 0.6.x branch, but since I
started with the 0.5.x code, I wanted to get that completed and working
before moving to the current code. With any luck, I should be able to
start porting this to 0.6.x by the end of the month.

	I've been following this for a while, but there is one thing
that I haven't been able to figure out.
	Is your work going to be imported into hostapd once you are
done, or are you just working on your own? :)

		I have uploaded the latest patch against 0.5.10 that
finishes off most
		of the missing features. In addition to the DLink, this
code now works
		with the Netgear WNDR3300 as well as AP reference
designs from Atheros
		and Broadcom. There was also a minor change to the
network block that is
		described in the PDF. Changes include
		
		- Added UUID-E as a network block field
		- Added BSD driver support
		- Don't assume EAP-Failure always means success
		- Restructure BSS selection
		- Handle unaligned address correctly when parsing fields
		- Populate M1 message with information from wpa_ssid
struct
		- Add NACK creation and processing
		- Support both PSK and passphrase variants of the
network key element
		- Validate R-SNonce[12] elements
		- Validate Authenticator and Key Wrap Authenticator
elements
		- Validate correct decryption of AES-CBC with padding
		- Differentiate between syntactical errors and
authentication errors in
		message processing
		
		I had hoped this would be the final update before
porting this to the
		0.6.x code base, but external registrars have thrown a
kink in that
		plan. So look for one more 0.5.10 based patch next week.
As always, you
		can find the latest patch on SourceForge
