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.

work (as opposed to BTN_LEFT, etc.)

All of this is always the same steps, let's use a macro so we can limit
our code to the bits we actually need to do.
This requires renaming some of the protocol itself to match up with the
expectations - not the worst thing since it makes the protocol more
consistent.

This gets rid of one layer of indirection with the struct message in
between - we can now call from the proto parser into the handling code
directly.

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.

With keymap messages, we may get and process data on the wire
but it doesn't necessarily result in a visible event. We need to enter
dispatch again to process the data in the next packet.

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 isn't something that libei itself uses but clients like synergy
need to know about this to be able to map relative pointer motion from
one host into the right physical pixel on another host.
This is required for mutter in the x11-compat mode where a 4k screen is
logically twice the size of a 2k screen, despite having the same
physical size.

This is required for supporting synergy/barrier and similar clients.
Replacing the touch and pointer range we now have server-defined
rectangular regions that specify the active zones for this device.
For example, a dual-monitor EIS server would create two touch devices
with one region each for the respective monitors - libei-generated
touches would thus fall on the right area of the monitor. Or just one
device with one region if the second screen should be inaccessible.
A relative device may have multiple regions since it can reach all
screens in the layout.
This leaks the screen layout to libei but that is necessary for the
functionality to work. A libei client may need to control devices
through absolute coordinates and it needs to know where screen
transitions from one to the next screen happen:
+-----------++----------------+
| || |
| B||Q |
| |+----------------+
| |
| A|P
+-----------+
In the above example, position P is unreachable and a client that
controls input on both screens must know that it cannot transition from
A to P but it can transition from B to Q.
