Prints out a YAML-compatible list of events for debugging.
This tool also takes a --socketfd argument which names the fd number
that the EIS connection is on. This allows the tool to be started from
some other process that does the EIS connection, e.g. a portal
implementation.
Previously, a client could only bind to a capability immediately after
SEAT_ADDED and with a rather awkward API to confirm the capabilities.
Change this to allow for dynamic binding of capabilities, i.e. a client
calls ei_bind_capability() or ei_unbind_capability() whenever it feels
like, causing the respective devices of this capabilty to be added or
removed.
This allows for clients that are temporarily disinterested in a
capability but may require said capability later.
The default function takes one capability, a helper for enable/disable
multiple capabilities in one go is provided as well. On the protocol,
only the "bind" request exists which always represents the currently
wanted set of capabilities.
Note that the helper functions for multiple capabilities require NULL
(not zero) as sentinel, thanks to gcc.
Our API requires a client to know which capability to pass into the
drop_capabilities function. This doesn't work for capabilities newer
than the client's version so they do not get disabled. The client will
thus receive devices it didn't ask for and doesn't know how to handle.
Let's invert the requirement and require the caller to confirm the
capabilities it wants - all others are dropped.
This is an API break but also requires updates of all clients, the
previous simple case of just calling ei_seat_bind() will now result in
zero capabilities.
Starting the demo client with --passive initializes a passive context,
and the server will send events to any active context.

One macro that also defines the cleanup function, one macro that only
defines the unref. This is required for any place where we want to
use cleanup from multiple source files - like the test suite.
Let's not force users/developers to dig through the commit log to figure
out what each tool does.

The latest version of the portal communication adds session capabilities
and wraps the calls a bit differently.
This now also includes a helper tool for the impl.portal part so we can
run xdg-desktop-portal against that without the need for a mutter
implementation.
Use:
- run the eis-demo-server
- run the eis-fake-impl-portal
- run the xdg-desktop-portal (it'll use the fake impl portal)
- run an ei client with the portal enabled
Note that the ei-fake-portal is a shortcut, it will open eis directly
without going through the impl.portal.

This effectively provides the EIS implementation with a notification
that the client will actually send events in the near future. To be used
by e.g. synergy-like clients when the pointer enters the logical screen
so that the EIS implementation can flash a warning or something.

Already present in e.g. libinput and wayland, this event allows us to
group several events together to denote them as a logical group.
Required for multi-touch but as we've learned with Wayland it's also
required to group other events (scroll events in the case of Wayland).

There's nothing in the protocol to modify the client device state from
the server, so a pause/resume cycle must leave the client with the
same(-ish) state. Pause is really just that, a short "no event now
please". Anything that would require e.g. modifying the device state by
releasing keys or buttons should result in the device being removed and
re-added.

This keeps most of the current structure but gets rid of client-side
keymaps (which have been broken since the server-side devices anyway).
The new approach: clients get a keymap (or NULL) from the server, if
they don't like it they will have to do transformation on their side.

This is slightly inconsistent with the configure API but more consistent
with the device API (which also has a new() + add()). It reduces
potential bugs though because the region cannot be added to two devices
anymore, and this way we also get a context in the region from the start
(which means we can log).

This changes the protocol so that it is the EIS implementation that
creates devices within a seat.
A client now "binds" to a seat and the EIS implementation creates
devices matching the requested capabilities. A client can close a device
if it no longer wants those but otherwise everything (including pointer
ranges) is handled by the server.
This is one giant patch because changes at the protocol level cannot
easily be broken out into smaller patches. Some FIXMEs are left which
will be handled in follow-up patches, e.g. the keymap handling is
basically broken right now.

The uinput path ended up diverged from the printf codepath and does not
create any seats and we can't process events.

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

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.
