We should follow telepathy-qt4's lead on this, since I already designed this
feature once :-)

I'm no longer sure that we want high-level API for channel creation on the
Connection, since the Right Way™ is now to use the ChannelDispatcher.

As medium-level API, we should have methods similar to the proposed ones (with
an a{sv} parameter), but on the TpAccount (as an implementation detail, they'll
talk to the channel dispatcher).

As high-level API, in telepathy-qt4 we have API on the Tp::Account like this:

PendingOperation *ensureTextChat(QString contact_id, ...);
PendingOperation *ensureTextChat(Tp::Contact contact, ...);

and similar for ensureMediaCall, ensureTextChatroom, etc. As we gain
higher-level API for more channel types, we'll also have createFileTransfer,
createContactSearch and so on.

We'll only wrap the mode (create/ensure) that is more useful for a particular
channel type - for calls and chats you almost always want to ensure, for file
transfers and contact searches you always want to create.

There is more prior art in libmcclient.
