Add functions to return the "bits of security" for various public key
algorithms. Based on SP800-57.

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.

Add support for DH parameter generation using DSA methods including
FIPS 186-3.

Make DHparams_dup work properly with X9.42 DH parameters.

RFC5114 parameters and X9.42 DH public and private keys.

Update/fix prototypes in fips.h

the FIPS capable OpenSSL.

from DSA copy q across and if q present generate DH key in the
correct range.

that use it.

now print out signatures instead of the standard hex dump.

More complex signatures (e.g. PSS) can print out more meaningful information.

Sample DSA version included that prints out the signature parameters r, s.

[Note EVP_PKEY_ASN1_METHOD is an application opaque structure so adding
 new fields in the middle has no compatibility issues]

Fix to make DHparams_dup() et al work in C++.

For 1.0 fix the final argument to ASN1_dup() so it is void *. Replace some
*_dup macros with functions.

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.

OPENSSL_NO_DEPRECATED, etc. Steve, please double-check the CMS stuff...
