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.
