This moves all systemd code into uterm_systemd.[ch]. This removes all the
ugly #ifdef's.
Furthermore, this fixes some hidden bugs in the previous implementation
and makes use of sd_booted() to see whether runtime systemd is really
available.

We used to simply probe every GPU that is reported by the kernel. However,
if a system has multiple GPUs that share display controllers, we cannot
use both simultaneously. Unfortunately, the kernel currently does not
notify us about this. Hence, we use some heuristics to determine which GPU
is the boot-gpu/primary-gpu.
This only adds the detection logic, it does not modify any code to use
this detection at all.

If libfuse is available then kmscon is built with a new session type: cdev
This session creates a fake TTY char-dev via CUSE (which itself uses FUSE)
which then can be used by user-space as if it were a real VT.
This is still incomplete and does only support basic I/O, yet. But it
shows in what direction this is going.

We build several tools inside of this repository and we need to make sure
all dependencies are met. Furthermore, we must make sure that default
values are recognized even on dependencies.
Hence, this reworks the whole configure.ac handling and does some renaming
of the constants that are used all over the source.
We need to test this some more weeks, but it should finally be a proper
autotools handling that we can release with kmscon-6.

The dummy session is a very simply session implementation that simply
draws a black background. It will be used by each seat as fallback if no
other session is available. If we didn't do that, we wouldn't be able to
guarantee that the screen is cleared after a session is unregistered.

We needed these files before libxkbcommon had a function to convert
keysyms to unicode, and then for the 'plain' keyboard backend, which
didn't use libxkbcommon. Since this backend was removed, these files are
no longer needed.

This adds a wayland compositor which registers sessions for each top-level
window within kmscon. This means, you can run any arbitrary
wayland-application on kmscon. Each top-level window that is registered by
the applications is put into a separate session and you can switch between
the sessions with the previously introduced session-shortcuts.
The compositor is still very basic. It doesn't support input devices at
all (not even talking about DnD). The only thing it does is surface
management (and even that is not fully implemented).
However, this shows the direction that kmscon will go. You can run the
Wayland "simple-shm" and "simple-egl" demos on kmscon to see how it works.

On seats other than seat0 we do not have any session-management, because
VTs are not available. Furthermore, if we want to get rid of CONFIG_VT
entirely, we also need to provide session-management for seat0.
This commit introduces sessions. Every seat (seats are now managed in
kmscon_seat.c) can have registered sessions. One of the sessions is active
and gets control over all displays. Session switching is entirely handled
inside of kmscon so there is always an active session (except if no
session is registered at all).
This also reworks the seat-management. kmscon_main.c now only manages the
seat allocation/deallocation and video-objects. The seat itself is handled
inside of kmscon_seat.c and does not know of uterm_video objects. Instead,
it is assigned a list of displays that it can use. Everything is still
hotplugging capable so user-experience should be the same as before.
The kmscon_terminal layer is reworked to be session based. So every
terminal is now a single session. By default, a single terminal-session is
created for each seat. This may be changed, though.
There is currently no input-control to change between session with
keyboard hotkeys. However, this will be added when we have more than one
session.

Configuration handling is totally independent from kmscon_main.c so we

This also does some basic initialization in kmscon_conf.c which is solely
related to configuration handling and logging.

When adding new elements, we should add them at the tail, not at the
front. And when removing elements, we should remove them from the tail,
too.
We also convert the whole stuff to the shl_dlist API so we do not have to
manage the linked-list ourself.
Note that this silently breaks the idea of having multiple listeners with
the same function+data in the hook. This is because removing the listener
may now change order of two identical entries, as we don't know which of
them to remove. That means, when adding two identical entries, you cannot
rely on them to retain their position in regard to each other.

We really need xkbcommon. There is so much stuff (including parsing of
keyboard shortcuts in conf.c) that depends on it. Therefore, we make it
mandatory now which allows us to use xkbcommon functions all over the
place.
Note that xkbcommon itself has no runtime dependencies so it is a small
self-contained library. The only reason I didn't do this ealier is that
xkbcommon has not seen a public release, yet. However, that should be done
in the near future.

The getty variants out there (including agetty) require an relative path
to the /dev directory as argument. This is really odd but we want to be
backwards-compatible to them so we allow this, too.
--vt now accepts:
* A positive number which is internally converted into /dev/ttyXY
* A string that does not start with '/' or '.' which is interpreted
relative to /dev as /dev/%s
* Everything else is interpreted as path
This option still selects only the TTY on seat0. On all other seats we do
not use controlling TTYs.

Sorry for the big commit, but I was working on the wlterm application and
then thought I can rework the whole configure-logic again. This mainly
renames all build-defines to BUILD_DEFINE_* and BUILD_HAVE_* and allows
specifying which applications to build via --enable-kmscon/--enable-wlterm
and similar.
wlterm is a new application which is a native wayland client with no
external dependencies. It serves several purposes:
* It uses TSM (not yet implemented, but will come soon) to create a
console independent from kmscon. This shows how TSM can easily be used
to create independent terminal emulators.
* It is a native wayland application (probably the first independent
wayland app so far?) and is used to test how well the wayland API
works. As wayland is still under heavy development, we need more
application-writers who report back whether the wayland-API makes
sense to them and whether it works correctly.
* A proper terminal-emulator for wayland! There is currently no proper
emulator so we really need something that we can work with.

We sometimes need to test what keys a client receives when specific keys
are pressed. This small helper simply runs in a terminal and receives raw
keyboard input and prints it to stdout with debugging information.
This can definitely be improved with the help of the TSM state-machine to
print more useful information and directly parse the input. However, this
is better than nothing.
