Also improve the generic HTTP client w.r.t. proxy and no_proxy options. Certificate Management Protocol (CMP, RFC 4210) extension to OpenSSL Also includes CRMF (RFC 4211) and HTTP transfer (RFC 6712). Adds the CMP and CRMF API to libcrypto and the "cmp" app to the CLI. Adds extensive documentation and tests.
