Whitespace issue originally, but let's fix it so that clang no longer
complains about missing initializers.

There is data that libei and the EIS implementation will want to
exchange that is not covered by the immediate API.
To avoid having to add APIs for all of these, let's provide a generic
property API that both server and client can use to exchange this info.
The property API provides read/write/delete permissions but those only
apply to the client, not the server. The idea is that a server can
create (or restrict) properties that the client can read but not modify
and/or delete. A special-case are properties filled in automatically by
libei: ei.application.pid and ei.application.cmdline. These could be
used by e.g. the portal implementation to match permissions.

This allows us to transmit extra information about the client before the
server has to decide on whether it wants to connect us.

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.

This allows a client to trigger kinetic scrolling (or prevent it).
For compositors implementing EIS, the only realistic scroll source is
continuous which allows for scroll stop events. So let's give the client
the opportunity to trigger those on demand.

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).

Since the server controls the keymap, and that keymap is likely merged
with some other device let's add the events so we notify the client of
things like numlock-is-down etc.

All the switch cases return early, moving it here means we can drop the
default case and have the compiler warn us about missing cases.

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.

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).
