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.

If the peer's channel list in negotiated handover does not have any
common channels and the local end is configured with an alternative
channel list, try to initiate another negotiation handover with the
alternative channels.

Be clearer about only a tag read being allowed when dpp-nfc is
configured to not allow connection handover.

If the local device becomes the handover selector, make the debug log
entries about client functionality not receiving the response clearer
since that is not really an error case.

Allow any channel to be used by not including a specific single channel
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.

Wait up to 100 ms for own handover request transmission to succeed if
peer handover request is received, but own crn is not yet available.

Convert most print() calls to use the summary() helper so that the
printed information gets written into a log file as well. In addition,
start using a mutex lock to synchronize debug prints between threads to
avoid merging of messages from different contexts.

Address possible handover request collisions for cases where both
devices try to initiate handover simultaneously.

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.

This was previously done only for the negotiated connection handover
case, but the same parameters are useful for the tag reading cases (URI
record and static handover).

Add more parameters to dpp-nfc.py to allow it to be used with more
detailed control by the caller. This allows Enrollee/Configurator roles
to be selected and Configurator parameters to be specified on the
command line.

This Python script is an example on how nfcpy can be used to drive an
