Remove legacy sign/verify from EVP_MD.

This removes m_dss.c, m_dss1.c, and m_ecdsa.c and the corresponding
public API EVP_{dss,dss1,ecdsa}().

This is basically the following OpenSSL commit. The mentioned change in
RSA is already present in rsa/rsa_pmeth.c.

commit 7f572e958b13041056f377a62d3219633cfb1e8a
Author: Dr. Stephen Henson <steve@openssl.org>

    Remove legacy sign/verify from EVP_MD.

    Remove sign/verify and required_pkey_type fields of EVP_MD: these are a
    legacy from when digests were linked to public key types. All signing is
    now handled by the corresponding EVP_PKEY_METHOD.

    Only allow supported digest types in RSA EVP_PKEY_METHOD: other algorithms
    already block unsupported types.

    Remove now obsolete EVP_dss1() and EVP_ecdsa().
