wireproto: add transport specific capabilities in the transport
We add a method to the protocol handler interface that allows
specific implementations to add their own capabilities.
The SSH implementation is a no-op.
The HTTP implementation adds the HTTP-specific capabilities.
The end result is transport specific capabilities now live in the
transport code instead of in some generic function in the wireproto
module.
