Similar to Bug #13422, but when you don't want to handle the channel yourself.

There are two major use cases:

* Fire and forget (Bug #29456): the initiating app only cares that its request
succeeded

* pseudo-observer: either requires extra support from the spec and Mission
Control (see Bug #25018), or various unreliable contortions involving being a
temporary observer with an inherent race condition (see the same bug).

This bug is for the pseudo-observer case.

I suspect it's not worth supporting the temporary observer thing, since as Bug
#25018 points out, it's inherently racy. Instead, we should fix Bug #25018,
provide a new requesting method that will fail if your MC is too old for it
(probably by fixing Bug #28866 at the same time), and make this telepathy-glib
API (which would maybe be called
tp_account_channel_request_ensure_and_observe_async()?) use it.
