wireproto: add out-of-band error class to allow remote repo to report errors

Older clients will still print the provided error message and not much else:
over ssh, this will be each line prefixed with 'remote: ' in addition to an
"abort: unexpected response: '\n'"; over http, this will be the '---%<---'
banners in addition to the 'does not appear to be a repository' message.

Currently, clients with this patch will display 'abort: remote error:\n' and
the provided error text, but it is trivial to style the error text however is
deemed appropriate.
