66d74626ba dpp-nfc: Reuse the same handover client for alternative URI
Postpone closing of the handover client to allow the same client to be
used for sending both handover request messages if an alternative URI
needs to be tried.

e9c192ffc7 dpp-nfc: Ignore (no) response to initial handover request
If an alternative proposal (second handover request) is sent, the

ignored.

7d27bcb8e7 dpp-nfc: Do not allow more than one alternative channel proposal
This avoids potential loops of endless alternative URI exchanges over
NFC negotiated connection handover. Only allow one such alternative
proposal and declarare the handover as a failure if another alternative
were needed.

6eaee933d7 dpp-nfc: Add test mode for negotiated connection handover
Allow all actual DPP processing steps in wpa_supplicant to be skipped by
specifying hardcoded URI values. Also allow a hardcoded crn to be
specified to force specific handover requestor/selector roles.

09c22bb782 dpp-nfc: Fix regression in NFC Tag writing

288c0ffaaa dpp-nfc: Do not hardcode netrole for NFC Tag writing cases
Allow netrole to be specified for NFC Tag writing cases. Previously,
this was hardcoded to use netrole=configurator when starting the listen
operation. Now the netrole parameter is not included by default, but any
netrole value can be specified with the new --netrole command line
argument.

In addition, fix the listening frequency for the case where a channel is
picked.

c9dc075fcd dpp-nfc: Fix connection handover renegotiation
The use of the alternative channel list did not work properly for the
case were both ends were trying to initiate the negotiated connection
handover. Fix this by always starting a new connection handover client
thread for sending the alternative proposal and ignoring peer messages
(likely something from the first attempt) during this modified attempt.

in the handover request without a need (for AP mode, use the current
operating channel). When sending out the handover select, pick a single
channel if no specific channel has been negotiated.

9ad3fe9343 dpp-nfc: Start handover server regardless of init-on-touch setting
The previous version was trying to force the handover roles based on the
--init-on-touch parameter on both sides. That is fine for some test
scenarios, but not appropriate for more normal use cases. Change this
design to enable handover server in all cases and only control starting
of the handover client based on --init-on-touch.
