First, assume that you require a connection ID at the server.  The general case for packets sent by clients in gQUIC is 0b00pp1000.  The change to short headers in this PR makes the typical IETF QUIC type byte 0b00k111pp, though obviously we don't make any promises about those 1 octets (and we will probably want to grease them).

One possible strategy we could pursue here is to disable greasing until we wean people off gQUIC.  Or - perhaps better - negotiate greasing.  Actually, I like that second idea, because it suits Colin's use case very nicely.
