    build: Do not use headers on library building
    
    Headers are not necessary to be passed to the library compilation
    function because the compiler will find them. On the other hand
    they are necessary for the proper GIR generation.
    
    This patch splits headers and sources, uses only sources for the
    library building and uses both for GIR generation. It also allows
    getting both separately.
