e294a73d0c DPP: Use crypto_ec_key_parse_pub() in dpp_get_subject_public_key()
The extra validation steps through the OpenSSL X509 API are not really
necessary here and they most duplicate checks that happen implicitly
within d2i_PUBKEY() and the EVP_PKEY_get0_EC_KEY() checks in
crypto_ec_key_parse_pub().

0517948d77 DPP: Replace EVP_PKEY by struct crypto_ec_key
To remove direct dependency to OpenSSL in DPP replace EVP_PKEY
by struct crypto_ec_key in all structures and function prototypes.

All direct calls to EVP_PKEY_free() are replaced by calls to
crypto_ec_key_deinit().

c6d0e5a93d DPP2: Add E-id in Reconfig Announcement
Add an encrypted Enrollee identifier into Reconfig Announcement frames
and decrypt that on the Configurator side. The actual E-id value is
currently not used for anything, but it can be used in the future to
provide better control over reconfiguration.

e5be6e68c8 DPP2: Add Enrollee netAccessKey group into Reconfig Announcement
This was added to the protocol design to support cases where the
C-sign-key uses a different group than the netAccessKey. The Enrollee
now indicates its netAccessKey group in Reconfig Announcement and the
Configurator builds it own reconfig Connector using that group instead
of the group used for the C-sign-key.
