Remove SSLv2 bindings.

This commit removes bindings that allow users to set SSLv2 handshake
methods. These are regarded as unnecessary and out-of-date: see #2527.
This commit does leave in a few options that refer to SSLv2 in order to
avoid breaking deployments that rely on them, and in order to allow
users to continue to request that SSLv2 not be enabled at all in their
OpenSSL.
