Clean up the EC key/curve configuration handling.
Over the years OpenSSL grew multiple ways of being able to specify EC keys (and/or curves) for use with ECDH and ECDHE key exchange. You could specify a static EC key (SSL{_CTX,}_set_tmp_ecdh()), use that as a curve and generate ephemeral keys (SSL_OP_SINGLE_ECDH_USE), provide the EC key via a callback that was provided with insufficient information (SSL{_CTX,}_set_tmp_ecdh_cb()) or enable automatic selection and generation of EC keys via SSL{_CTX,}_set_ecdh_auto(). This complexity leads to problems (like ECDHE not being enabled) and potential weird configuration (like being able to do ECDHE without the ephemeral part...). We no longer support ECDH and ECDHE can be disabled by removing ECDHE ciphers from the cipher list. As such, permanently enable automatic EC curve selection and generation, effectively disabling all of the configuration knobs. The only exception is the SSL{_CTX,}_set_tmp_ecdh() functions, which retain part of their previous behaviour by configuring the curve of the given EC key as the only curve being enabled. Everything else becomes a no-op. ok beck@ doug@
