Scott Lamb e9a5e4e34a overhaul error type
*   stop using deprecated failure crate and its deps

*   more uniformly detailed error messages

*   an enum of the type of error, currently internal-only. I'm not
    confident enough I understand what cases a caller might want to
    distinguish, so I added a comment inviting input instead of
    exposing it now.

*   while I'm at it, separate connection context and message contexts.
    This shrinks some of the data memmoved around in PacketItem and
    CodecItem.
