Implementation of a generic wrap interface for bignum and diffie-hellman based upon Damien's wrap code in openssh-openbsd. This commit adds the generic interface along with the backing code for openssl, cng, and cng with an openssl fallback. Currently, openssl is the only provider for bignum and the diffie-hellman generic interface is only for static and negotiated oakley groups..
