    Bug 1156: Seperate DRM/GBM NEWT native library from main head NEWT native library
   
    DRM/GBM is enabled for Linux in general.
    Nativewindow's 'nativewindow_drm' DRM/GBM native library is already seperated.
   
    NEWT get its 'newt_drm' DRM/GBM native library.
   
    NEWT's main head native library is renamed from 'newt' -> 'newt_head'
    and is earmarked for further seperation similar to Nativewindow's.
    At least a 'newt_wayland' will probably followup when support is added.
   
    Goal is to remove DRM/GBM dependency for Linux X11 operation
    as well as removing X11 dependency for Linux DRM/GBM operation.
