BUG/MEDIUM: connections: Split CS_FL_RCV_MORE into 2 flags.
CS_FL_RCV_MORE is used in two cases, to let the conn_stream
know there may be more data available, and to let it know that
it needs more room. We can't easily differentiate between the
two, and that may leads to hangs, so split it into two flags,
CS_FL_RCV_MORE, that means there may be more data, and
CS_FL_WANT_ROOM, that means we need more room.
This should not be backported.
