Requesting a channel from the channel dispatcher can take some time, so an
object is created in the channel dispatcher to represent each request. This
proxy represents one of those objects.

<p>
Any client can call <a class="link" href="telepathy-glib-channel-request.html#tp-cli-channel-request-call-cancel" title="tp_cli_channel_request_call_cancel ()"><code class="function">tp_cli_channel_request_call_cancel()</code></a> at any time to
