To cut down on the boilerplate, an unref-able struct variable can now be
declared as
_unref_(type) *name = NULL;
which is the equivalent of
_cleanup_(type_unrefp) struct type *name = NULL;
Let's see how that style ends up reading.
This means we can get rid of the custom _cleanup_foo_ functions everywhere, no
need for all the extra #defines etc. A somewhat special case is systemd which
defines the various unrefp functions for us in the headers, so we can use them
directly.
OBJECT_IMPLEMENT_UNREF now also creates the unrefp function for this object -
this of course conflicts where DECLARE_UNREF_CLEANUP_FUNC is in scope. Not a
problem so far, let's see how we go.

After CONNECT, the EIS implementation needs to add one or more seats. The
libei client can only create devices within those seats. This mirrors the
wayland hierarchy as well as the X.Org one.
The seat has a set of allowed capabilities, so the client knows ahead of time
when it may not be possible to create a specific device.

This fits better with the rest of the API and also fits much nicer into the
most common use-case of "device doesn't have a keymap".

Client-side the approach is a managed touch object rather than passing the
touchid around. This is intentional, it allows for a stackable API in the
future if we need to add things like pressure or major/minor to it.
On the server side the touches are managed through the event object anyway, so
we don't need the same abstraction there.

Because events may be in-transit when a client removes the device, we need to
make this a full roundtrip to the server. Otherwise the client may assume a
device is removed, releases all references and then gets the original device
added event for that device. Better to have this as a round-trip instead.
This requires the server to call eis_device_disconnect() on the removed
notifications but we do so during eis_event_unref() anyway in case the server
forgets.
And it changes some of the API behaviors, so adjust the tests for that.

This was already spelled out in the documentation but just not yet
implemented. New starting state for any device added by EIS is "suspended",
the server needs to explicitly resume it before events are accepted.

This function dispatches until a stable state is reached - that could be no
event waiting or some event waiting to be processed.
