The reverse case (local identifier configured but no identifier
received) was already covered, but PKEX is not going to complete
successfully if there is any difference in identifier configuration, so
ignore this other case as well. This avoids unnecessary responses to
PKEX requests with identifier from a device that is ready for PKEX in
general, but not for that particular request.

It looks like at least OpenSSL 1.1.0i includes the extra checks in
EC_POINT_set_affine_coordinates_GFp() that break the previously used
mechanism for generating invalid keys. Fix this by using the alternative
design that was used with OpenSSL 1.1.1 and BoringSSL.

This enhances DPP_AUTH_INIT, DPP_CONFIGURATOR_SIGN, and SET

At least LibreSSL v2.7.2 indicates support for OpenSSL API 1.1.0, but it
does not apparently use const ASN1_OBJECT * with X509_ALGOR_get0(). Use
the older non-const version here with LibreSSL to fix compilation.

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.

This prevents an issue where duplicated Authentication Response frame
could have resulted in deriving a new ke value after M.x had already
been cleared. This would result in the following configuration exchange
failing. This could happen since many driver do not filter out
retransmitted Public Action frames and link layer. Furthermore, this
could have been used as a denial-of-service attack agains the DPP
exchange.

Instead of using the all-zeros Initiator Bootstrapping Key Hash when no
local bootstrapping key is configuref for the Initiator, automatically
generate a temporary bootstrapping key for the same curve that the
Responder uses. If the Responder indicates that it wants to do mutual
authentication, provide the URI for the auto-generated bootstrapping key
in the DPP-RESPONSE-PENDING event for upper layers to display the QR

While the OpenSSL version of i2d_EC_PUBKEY() seemed to be able to use
the POINT_CONVERSION_COMPRESSED setting on the EC key, that did not seem
to work with BoringSSL. Since this is not exactly robust design, replace
use of i2d_EC_PUBKEY() with a custom routine that enforces the DPP rules
on SubjectPublicKeyInfo (compressed format of the public key,
ecPublicKey OID, parameters present and indicating the curve by OID).

This routine was previously implemented twice using i2d_EC_PUBKEY().
There is no need to duplicate that implementation and especially since
it looks like this implementation needs to be replaced for BoringSSL,
start by using a shared helper function for both locations so that there
is only a single place that uses i2d_EC_PUBKEY() to build the special
DPP bootstrapping key DER encoding.
