xdotool sends the events and disconnects immediately, Xwayland queues up those
events until it has a seat but then also disconnects immediately. Let's
emulate this behavior so we can catch breakages before Xwayland sees them.

Removing a seat could cause two device remove events to happen. Fix this by
splitting the removal up into two bits: removed by server and removed by
client. Only once both bits are set, remove the device.
This needs to happen in libei and libeis.

Add a debug marker to show any changes done during the final event processing,
and print the event name for wrong event types.

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.

The previous approach would implicitly allow any capability not known to the
server. Switch instead to requiring an explicit 'ok' for any capability the
server wants to support.

Naming scheme is now: ei_device_<capability>_get/set_<what>. So far the
range is the only one where we had to deal with the same thing for two
different capabilities and it's unlikely we'll have to have different keymaps
for different capabilities. But still, let's do this now while it's still
easy.

In case the RESUMED isn't written on the wire yet (or it's written with
sendmsg and thus a separate message on its own) we don't have the RESUMED
ready for us yet. Let's call another dispatch to make sure it's processed.

Where the server connects a device after the client has already removed it, we
need to ignore that message silently.

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.
