The logic behind this two-layer check is bogus and doesn't work. Merge
both layers so we have a proper dependency-check again. This will make the
error messages less verbose but at least it works again.

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

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.

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.

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.

wlterm needs xkbcommon as the wayland protocol depends on XKB states.
Hence, we add a hard-dependency for wlterm.
Signed-off-by: David Herrmann <dh.herrmann@googlemail.com>
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.

The bbulk renderer is very similar to the bblit renderer but it assembles
a request-buffer of all characters and then pushes these requests via a
vector-call to the video hardware.
This turns out to increase performance slightly as we do not call into the
video subsystem for every characters but only once.
This renderer can reduce performance when used with partial-redraws (which
are not implemented, yet), so we keep the bblit renderer around.

Upstream mesa renamed gbm_bo_get_pitch() to gbm_bo_get_stride(). As gbm

The old font-renderer was horribly slow. There were several ideas to
speed it up but I decided to add the pango backend again. Pango allows us
to draw combined-characters and all other kinds of special characters. We
would have to rewrite pango if we wouldn't want this dependency so I
currently have no idea why we should make it optional.
However, some people might not care whether they can correctly display all
kind of Unicode text but instead want some shiny kmscon without any
dependencies. Therefore, I will keep the old freetype font-renderer even
though it is not used yet. However, we can convert it at any time.
The new font-renderer is not used yet. We need to cleanup the console
layer first before it can be hooked into the terminal.
