Define LOG_ENABLE_DEBUG if we enabled debugging. The log subsystem uses
this to enable the log_debug() statements.

uterm_video can work with any backend so we need a DRM backend to get the
same functionality as our previous compositor/output API.

We recently moved log_warning to log_warn and I forgot to fix it when
merging the kbd-dumb backend. Fix this now.

The paths can be off when building out of tree, so have make put them in
for us instead. This requires turning the straight genshader.c file to a
template.

This commit adds a very simple keyboard backend which does basic keycode
interpretation. It is used as a fallback when xkbcommon is unavailable
or is not required.
See the file header for what is supported.

Currently it's required by xkbcommon. However, we will need it for other
backends as well, even with xkbcommon support disabled.
xproto consisted only of static header files. We use the XK_ keysym
definitions. It is therefore only required during compilation and we
shouldn't needlessly duplicate it ourselves.

OpenGL pulls in lot of X dependencies on linux. To avoid this we also
support OpenGLES2 now. This will also allow to run kmscon on
embedded/mobile platforms.
We still get X dependencies through EGL which we cannot avoid as EGL is
compiled with multiple backends on most systems. However, switching to
GLES2 reduces memory footprint by 30MB which is pretty good.
This also enables GLES2 as default in autogen.sh. However, default
behaviour of configure will still be GL.

We currently define NDEBUG only if --<set>-debug is not specified at all. That
is, --disable-debug currently has almost no effect.
This fixes this bug and also corrects a wrong parenthesis.

This is a first attempt of a freetype2 backend for the font drawing functions.
This avoids the heavy pango/cairo dependencies, although, we might lose
important font handling that pango does for us like correctly drawing combined
characters.
This is still a stub implementation. The drawing operations are not supported,
yet. Use --enable-pango during configure to enable the still working pango
backend.

This commit introduces a new kmscon_input_event structure which is
delivered to the input consumer. The information provided is
- The evdev scancode (=physical keyboard key).
- The X keysym (a symbol representing what the typist really intended).
- The active modifiers (e.g. Shift, Control..)
- The unicode (UCS-4) value, when it makes sense.
To achieve this we add two dependencies:
- libxkbcommon (this entails xproto and kbproto, but shouldn't bring any of
big X dependencies)
- A function to translate keysyms to unicode values (taken from xlib,
copied in-tree).
libxkbcommon is not an all-around solution, and requires various degrees
of supporting code, depending on how much we wish to support. This
commit implements the common, basic uses:
- Choosing layouts, variants and options
- Switching groups
- Switching shift-levels
- Setting modifiers
Though some stuff is missing. Further information in the comments.
test_input.c is updated to use the new input event interface. You can
change the layouts in input.c:init_input() and see what works and what
doesn't.

This does all the boring stuff for an input subsystem:
- Input device discovery using udev
- Input device hotplug (add/remove)
- Reading the evdev data from the devices
- Publishing input events to a callback through the eloop
- Suspending and resuming the input capture
Currently the delivered input events are basically just evdev's
"struct input_event" (type, code, value). More work is required to
have it pass out useful data.

- Use C99 and gnu extensions.
- Explicitly link against libdrm (more strict linkers like gold would
complain).
- Consistently use *_CPPFLAGS where due.
- Clear the default CFLAGS.

This commit adds basic autoconf + automake files to build the project.
It also adds a main.c stub in order to simulate the main binary.
The configure script uses pkg-config to find the libraries. The usual
stuff should work. The only additional option right now is:
./configure --enable-debug [To enable debugging symbols]
The Makefile should also support the standard stuff:
make [To build the kmscon binary]
make check [To build the test_* binaries]
make dist [To create a tarball]
make clean
make install
etc.
To start from a clean tree (e.g. git clean -dfx), do something like the
following:
./autogen.sh
./configure --enable-debug CFLAGS=-O0
make
It all should work well enough for now.
