Allow the Configurator to be configured to use a specific curve for the
netAccessKey so that it can request the Enrollee to generate a new key
during the configuration exchange to allow a compatible Connector to be
generated when the network uses a different curve than the protocol keys
used during the authentication exchange.

The TCP code path did not handle the postponed connection attempt on TX
status and the following result message from the Enrollee to the
Configurator. Fix this by adding TCP-versions of these operations to
match the way wpa_supplicant implemented this for the Public Action
frames.

Add support for PKEXv2 core protocol. This defines a new PKEX Exchange
Request message type with protocol negotiation and different rules for
key derivation with PKEXv2 or newer is used.
This does not change existing behavior for PKEX, i.e., the PKEXv1
variant will still be used by default.

Instead of generating EC point with random coordinates, generate a
valid EC point and then corrupt the coordinates after exporting them
in binary format.

Rewrite EC point/bignum computation done in PKEX protocol using EC
point/bignum primitives already defined in crypto.h and couple of small
new helper functions.

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().

Use ppKey instead of C-sign-key to encrypted E-id to E'-id into Reconfig
Announcement frame on the Enrollee side.

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.

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.
