The command line is too long.

Original issue's description:
> Record the XMPP error in remoting.FormatIq.
>
> This CL
> 1. Records the XMPP error type, jingle_action and error condition
>    in remoting.FormatIq.
>    This error is later extracted by the ClientSession to upload along
>    with session state change events.
>
>    We choose to record the error in the webapp instead of the plugin to
>    avoid adding new contract between the webapp and the plugin just for
>    the sake of debugging, especially when we are so close to branch point.
> 2. Removes some legacy fields in the FormatIq to avoid parse errors.
> 3. Parses the error before the original jingle message.  This ensures
>    addition of unrecognized Jingle fields like QUIC will not break the
>    error parsing.
