Build: promote daemons/configure.ac to top-level configure.ac
    
    Top-level Makefile is still not managed by Automake (e.g. hand-made).
    This is preparatory work. Other configure.ac files will be gradually
    merged into the top-level one. After that we will be able to throw-away
    the hand-made top-level Makefile and use Automake for everything.
