Add X9.42 DH KDF. Move sharedinfo generation code to CMS library as the
same structure is used by DH and ECDH.
Move ASN1_OBJECT typedef to ossl_typ.h so it can be picked up by dh headers
without the need to use ASN1.
(cherry picked from commit dc1ce3bc64)
Check and set AlgorithmIdenfier parameters for key wrap algorithms.
Currently these just set parameters to NULL.
(cherry picked from commit e61f5d55bc)
Add support for ECDH in enveloped data. The CMS ctrls for the EC ASN1
method decode/encode the appropriate parameters from the CMS ASN1 data
and send appropriate data to the EC public key method.

Don't check for binary curves by checking methods: the values will
be different in FIPS mode as they are redirected to the validated module
version.

knock-on work than expected - they've been extracted into a patch
series that can be completed elsewhere, or in a different branch,
before merging back to HEAD.
key ASN1 handling through a single EVP_PKEY_ASN1_METHOD structure and move
the spaghetti algorithm specific code to a single ASN1 module for each
algorithm.
