Future versions of OpenSSL use the canonical terms "ECDHE" and "DHE"
as configuration strings and compilation constants. This patch
introduces aliases so that the stable 1.0.2 branch can be
forward-compatible with code and configuration scripts that use the
normalized terms, while avoiding changing any library output for
stable users.
