9c1fbff074 DPP2: Generate a privacy protection key for Configurator
Generate a new key for Configurator. This is either generated
automatically for the specified curve or provided from external source
with the new ppkey=<val> argument similarly to the way c-sign-key was
previously generated.

c043b1e000 DPP: Remove unnecessary dpp_global_config parameters
These were not really used anymore since the AP/Relay case did not set
msg_ctx or process_conf_obj in the global DPP context. Get the
appropriate pointers more directly from the more specific data
structures instead and remove these global values.

While the listed unknown operating class/channel number pairs need to be

e780b4bf20 DPP: Bootstrapping via NFC URI Record
This extends hostapd and wpa_supplicant DPP implementation to allow the
bootstrapping URI to be generated for and parsed from an NFC Tag with an
NFC URI Record. This is similar to the way the bootstrapping URI is used
with QR Code for unidirectional authentication.

The DPP_BOOTSTRAP_GEN command uses "type=nfc-uri" to request the URI to
be assigned for NFC URI Record. In practice, the URI is generated
identically to the QR Code case, but the internal entry maintains the
NFC-URI type.

A new command "DPP_NFC_URI <uri>" can now be used to parse the URI read
from an NFC Tag with the NFC URI Record. This is similar to the
DPP_QR_CODE command.

Other commands (mainly, DPP_LISTEN and DPP_AUTH_INIT) are used for NFC
URI in the same way as they are used for QR Code.
