[Freeciv-Dev] (PR#12883) generate_packets.py bug: handle-per-conn doesn't work with handle-via-packet

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

If you set handle-per-conn for a packet in packets.def it is supposed to
cause the connection rather than the player to be passed to the packet
handler.  However with a handle-via-packet packet (declared either
manually or automatically [when the packet gets large enough]) the
handle-per-conn directive is simply ignored and the player is passed in
rather than the conn.

With the new civworld design this is a particular problem, since all
"edit" packets must be handled per conn and many will end up being large.
