[PATCH 4/6] send-pack: improve unpack-status error messages

[Jeff King <peff@peff.net>]

When the remote tells us that the "unpack" step failed, we
show an error message. However, unless you are familiar with
the internals of send-pack and receive-pack, it was not
clear that this represented an error on the remote side.
Let's re-word to make that more obvious.

Likewise, when we got an unexpected packet from the other
end, we complained with a vague message but did not actually
show the packet.  Let's fix that.

And finally, neither message was marked for translation. The
message from the remote probably won't be translated, but
there's no reason we can't do better for the local half.
