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".

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.

This is a basic example on how an EIS server can map to uinput, just to
illustrate that there's nothing in libeis that requires a display server
protocol (X or Wayland). All that's done here is we set up a keyboard and
pointer device and route the input events through that.

The current implementation of that portal has two methods: EmulateInput to
authenticate and Connect to get the fd to the EIS implementation. The portal
implementation is in charge of finding EIS and restricting it if need be.
This uses libsystemd because we can integrate that with epoll and our
libei_dispatch() method. GDBus requires a glib mainloop, so it's not really
suitable here. Given how simple this is anyway, it's easy to just do the DBus
bits in the caller and then hand the fd to ei_setup_backend_fd().
A eis-fake-portal is provided for testing, this "portal" can use the custom
portal bus name and connect the eis-demo-client to the eis-demo-server.

The logger utilities are useful for quick prototyping, but we've reached the
point where we need the "proper" implementation of a log handler.

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.

Same as already done for libei. There's relatively little benefit here since
we won't have a lot of different events and any caller will do the switch
based on the event type anyway. So let's just export a single event type and
have everything contained in that.
Since this required rewriting all getters, let's move the lot to a new file
and streamline things a bit that way.

The main reason for having different functions to create the initial context
was so we can nest the eis struct inside the context-specific struct. That
shouldn't leak into the API though.

The main reason for having different functions to create the initial context
was so we can nest the ei struct inside the context-specific struct. That
shouldn't leak into the API though and our use-case is probably one where we
create one context, then iterate through possible backends until one succeds -
having different contexts here doesn't help then.

We're in a library here, so expecting the caller to handle SIGPIPE just in
case we get it is a bit demanding. Let's use send() instead so we can just
prevent that altogether.

Better than the current "myclient". Lacks safety and whatnot so long-term it

This is the minimum framework to support connecting to a libeis server, adding
a device and sending relative pointer motion events.It's missing a bunch of
checks and verifications, many of the hooks are still missing, etc.
See the tools/ directory for an example. The protocol is as outlined in
commit f7a24b2fbd.
