[PW_SID:790210] RFC: PKEX support for DPP

[IWDTestBot]

PKEX is part of the WFA EasyConnect specification and is
an additional boostrapping method (like QR codes) for
exchanging public keys between a configurator and enrollee.

PKEX operates over wifi and requires a key/code be exchanged
prior to the protocol. The key is used to encrypt the exchange
of the boostrapping information, then DPP authentication is
started immediately aftewards.

This can be useful for devices which don't have the ability to
scan a QR code, or even as a more convenient way to share
wireless credentials if the PSK is very secure (i.e. not a
human readable string).

This only documents the DBus API for now to get an idea of how
and where this module would live. The current plan is to keep
it in dpp.c. This module is getting rather large but all the
infrastructure exists for offchannel/frame callbacks and
state so it makes sense to keep it there. The plan is to add
some additional states to dpp for PKEX which would happen
prior to AUTHENTICATION and allow the PRESENCE state to be
skipped.

PKEX would be used via the two DBus APIs. PkexConfigure would
start listening and wait for an Enrollee to send a PKEX
exchange request. The enrollee would be started with PkexEnroll
and initiate the exchange. PKEX would proceed and once done
DPP Authentication would start using the boostrapping keys
exchanged.

For convenience/security the PKEX key could be specified in the
IWD provisioning file (part of the Security group). This would
allow IWD to encrypt it and avoid the need for some other entity
to store the key in order to call PkexConfigure (e.g. if not
initiated by a human entering the key).
