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.

c02dd10d76 DPP2: wpa_supplicant as Controller over TCP
New wpa_supplicant control interface commands "DPP_CONTROLLER_START
[tcp_port=<port>]" and "DPP_CONTROLLER_STOP" can be used to start and
stop listening to DPP requests over TCP in the Responder role. The TCP
connections are processed similarly to the ones that would have been
received over DPP Public Action frames.

87d8435cf9 DPP: Common configurator/bootstrapping data management
Merge the practically copy-pasted implementations in wpa_supplicant and
hostapd into a single shared implementation in dpp.c for managing
configurator and boostrapping information. This avoid unnecessary code
duplication and provides a convenient location for adding new global DPP
data.

8179ae3a2a DPP: Support retrieving of configurator's private key
To retain configurator information across hostapd/wpa_supplicant
restart, private key need to be maintained to generate a valid pair of
authentication keys (connector, netaccess_key, csign) for new enrollees
in the network.

Add a DPP_CONFIGURATOR_GET_KEY control interface API through which the
private key of an existing configurator can be fetched.

Command format:
DPP_CONFIGURATOR_GET_KEY <configurator_id>

The output from this command can then be used with
"DPP_CONFIGURATOR_ADD key=<hexdump>" to create the same key again.

c1d3773967 DPP: Stop authentication exchange of DPP_STOP_LISTEN
Previously, this command stopped listen operation immediately, but if
there was an ongoing authentication exchange, a new listen operation was
started. This is not really expected behavior, so stop the
authentication exchange first with this command to avoid restarting
listen operation.

be27e185b7 DPP: Bootstrap information management
Add wpa_supplicant control interface commands for parsing the bootstrap
info URI from a QR Code (get peer public key) and to generate a new
bootstrap info with private key for local use. The optional
key=<hexdump> argument to the DPP_BOOTSTRAP_GEN command can be used to
specify the bootstrapping private key in OpenSSL ECPrivateKey DER
encoding format. This results in the local bootstrapping information
entry being created with the specified key instead of generating a new
random one.
