When WPS is used with NFC connection handover, the AP may indicate its
operating channel within the credential information. Use this
informatiom, if present, to speed up the scan process.

Previously, only the maximum length 32 octets for OOB device password
was accepted. Since the specification allows a shorter password to be
used with limited OOB mechanism (e.g., small NFC tag), we should accept
lengths 16..32.

Make the P2P code keep track of WPS vendor extensions received from
peers so they can be exposed via DBus later.

At least D-Link DIR-600 and DIR-825 have been reported to include
an extra octet after the Network Key attribute within a Credential
attribute. This can happen at least when they are provisioning an
open network.
Add a workaround to detect this incorrectly encoded attribute and
to skip the extra octet when parsing such a Credential.
The WSC 2.0 specification moved to use another design for the new
attributes to avoid backwards compatibility issues with some
deployed implementations.
This adds definitions and parsing of the new attributes that were added
in WPS 2.0. In addition, the version negotiation is updated to use the
new mechanism, i.e., accept everything received and use the new Version2
attribute in transmitted messages.
Use shared functions for converting Primary Device Type between binary
and string formats. In addition, use array of eight octets instead of a
specific structure with multiple fields to reduce code complexity.
