Add crypto_ec_key_get_ecprivate_key() function in crypto.h and use it
when possible in DPP code.
This function converts a struct crypto_ec_key into a DER encoded ASN.1
ECPrivateKey.

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().

The allocated memory pointed by the pem pointer was freed on an error
path without clearing the pointer to NULL before returning it from the
function. This could have resulted in use of freed memory in an error
case. Fix this by clearing the pointer so that the function returns NULL
properly in the case of this error.

In theory, the EVP_PKEY_get0_EC_KEY() could fail, so verify that it
succeeds before using the pointer to get the group.

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

This was changed in the protocol design to include nonce from both
devices, so update implementation to match.

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.

Parse the received CSR, verify that it has been signed correctly, and
verify that the challengePassword is present and matches the derived cp.

Add initial Enrollee functionality for provisioning enterprise (EAP-TLS)
configuration object. This commit is handling only the most basic case
and a number of TODO items remains to handle more complete CSR
generation and config object processing.
