Create TSM screens and VTE objects plus a PTY and connect everything so we
have a working terminal. Keyboard input still needs to be hooked up and
the drawing functions aren't implemented, yet.

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.

There is absolutely no need to use kmscon-static anymore so move it into

We need a copy of xkbcommon-keysyms.h as long as xkbcommon is not included
in all major distributions. We _need_ this build-time dependency,
otherwise, we cannot build the other keyboard backends.
However, requiring xkbcommon as build-time dependency is not a solution as
no major distribution includes it.

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.
Signed-off-by: David Herrmann <dh.herrmann@googlemail.com>
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

This also moves the generated shaders into the static-kmscon library. The

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.
