This sets up ECDH key exchange, when compiling against OpenSSL that supports EC. Then the ECDHE-RSA and ECDHE-ECDSA cipher suites can be used for SSL connections. The latter one means that EC keys are now usable. The reason for EC key exchange is that it's faster than DHE and it allows to go to higher security levels where RSA will be horribly slow. There is also new GUC option ssl_ecdh_curve that specifies the curve name used for ECDH. It defaults to "prime256v1", which is the most common curve in use in HTTPS.
