build: use gnu autotools

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.
