There are a number of instances throughout the code where the constant 28 is
used with no explanation. Some of this was introduced as part of RT#1929. The
value 28 is the length of the IP header (20 bytes) plus the UDP header (8
bytes). However use of this constant is incorrect because there may be
instances where a different value is needed, e.g. an IPv4 header is 20 bytes
but an IPv6 header is 40. Similarly you may not be using UDP (e.g. SCTP).

Allow ECDHE and DHE as forward-compatible aliases for EECDH and EDH

see RT #3203

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
