Add a new CurrentSupportedVersionsForClients() function to QUIC
which should be used by clients to determine the QUIC versions
they should speak. This list excludes obsolete versions, specifically
gQUIC and draft-29. Also adds IsObsoleteSupportedVersion() and
ObsoleteSupportedVersions().

Follow-up CLs will convert clients to use this new function.
