This never really worked and was horrible to maintain. We need to find
something else for documentation, but we will probably have to do it with
a separate XML file without any generator.

This makes the hook implementation independent of any other code or header
so you do not have to link to libkmscon-static when using it.

This creates a new header static_dlist.h which is independent of any other
code. It can be included by other libraries/applications without the need
of linkin to libkmscon-static which reduces a lot overhead.

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.

This adds a new Unifont font-backend based on the recently added Unifont
data. The backend is disabled by default for 2 reasons:
- It takes about 5min to compile and needs >1GB of memory on an Intel
Atom N450
- License situation is unclear as it is GPL

This new generator converts the unifont hex-encoded data into a C-source
file which then can be compiled statically into the kmscon binary. Please
note that the resulting source file is bigger than 100MB and can take
quite a while to compile.

Defining *_la_CPPFLAGS var in "if...endif" block breaks generation
of Makefile.in - automake assumes it's defined unconditionally and
uses it for building objects.
configure.ac clears all variables if each dependency is disabled so we can
include it unconditionally.

The fakevt helper binary can be used on VT-less systems or seats to make
kmscon activate the fake VT and deactivate it. This way, you can control
when kmscon acquires video devices and when it releases them.
This is a global setting that affects all seats where kmscon is running
except seat0 if it uses real VTs.
This should only be used for debugging. This is really no intended for use
in production.

This implements the static 2D blitting callbacks for the DRM backend. It

The genshader program now takes all input shaders as arguments so we can
easily add new shaders. We also name the constants after the shader file
to be as flexible as possible.
This also moves the generated shaders into the static-kmscon library. The
linker will strip unused symbols, anyway, so we aren't loosing anything
here.

We are in a state where redrawing the console can take a significant
amount of time on slower machines. Therefore, we definitely need gcc code
optimizations which help here a _lot_. However, they are currently bundled
to the debug flags.
This splits this into two options. We still need this flag to get getter
backtraces. Otherwise, those inlined functions are horrible to track done.

We no longer require glib, yeah! Drop the mandatory glib dependency from

We still have a not-mentioned pango dependency but this can be replaced
with freetype or a static font renderer so we currently do not care.

Nearly all drm drivers provide a GEM/TTM buffer backend called "dumb
