    Honour the packet size limit in bare-connection protocol.
    
    When I set up the simplified version of just the ssh-connection
    protocol we use for connection sharing, I carefully documented at the
    top of sshshare.c that packets in that protocol variant are limited to
    just over 0x4000 bytes. And did I remember to actually honour that, by
    restricting the sizes of outgoing packets when actually speaking the
    bare connection protocol? I did not.
    
    Well, better late than never. Here I introduce a packet size limit
    that can be imposed by the BPP, and arrange for sshconnection.c to
    take the min of that and any given channel's max packet size as sent
    by the remote end. All BPPs except ssh2bpp-bare set it to the no-op
    value of the largest possible uint32_t.
