ECDH_compute_key is silently ignored and the KDF is run on duff data

Thanks to github user tomykaira for the suggested fix.

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.

Add X9.62 KDF to EC EVP_PKEY_METHOD.

enhance EC method to support setting curve type when generating keys and add parameter encoding option

between NIDs and the more common NIST names such as "P-256". Enhance
ecparam utility and ECC method to recognise the NIST names for curves.

Check return value of ECDSA_sign() properly.

Initial support for CMS.

Add zlib compression BIO.

Add AES key wrap implementation.

Generalize S/MIME MIME code to support CMS and/or PKCS7.

Send ctrls to EVP_PKEY_METHOD during signing of PKCS7 structure so
customisation is possible.

functions and EVP_MD_CTX_copy work properly.

value of the passed output buffer is NULL.

The old method of using EVP_PKEY_size(pkey) isn't flexible enough to cover all
cases where the output length may depend on the operation or the parameters
associated with it.

Fix rsa_pkey_method.

Add digest size sanity checks.

need for a separate EVP_PKEY parameter in the other operation
initialization routines.

No method implementations yet.

of the EVP routines to public key algorithms.

I'll remember to try to compile this with warnings enabled next time :-)

This is currently *very* experimental and needs to be more fully integrated
with the main verification code.

Merge from the ASN1 branch of new ASN1 code
to main trunk.

Lets see if the makes it to openssl-cvs :-)

Update PKCS12_parse().

Make the keyid in certificate aux info more usable.
