wireprotov2: decode responses to their expected types
Callers of established wire protocol commands expect the
response from that command to be decoded into a data structure.
It's not very useful if callers get back a stream of bytes and
don't know how they should be interpreted - especially since that
stream of bytes varies by wire protocol and even the transport
within that protocol version.
This commit establishes decoding functions for various command
responses so callers of those commands get the response type
they expect.
In theory, this should make the version 2 HTTP peer usable for
various operations. But I haven't tested to confirm.
