Use named curve parameter encoding by default. 



Many applications require named curve parameter encoding instead of explicit
parameter encoding (including the TLS library in OpenSSL itself). Set this
encoding by default instead of requiring an explicit call to set it.

Add OPENSSL_EC_EXPLICT_CURVE define.
