avdtputil: Some minor cleanup and leak fixes
dfbvideosink: port to 1.0

including the following supports and fixes:

* Create DirectFB surfaces from GstBufferPool
* Add NV12 pixel format support
* Don't use the cursor in the exclusive mode
  - EnableCusor() can be only used when the administrative mode is set
    in DirectFB 1.6.0 and later.
* Support multiple plane rendering for planar color formats
  - This accommodates the chroma plane offsets of the framebuffer
    in planar formats.
* Invoke SetConfiguration regardless of video mode setting in setcaps()
  - SetConfiguration() method should be invoked regardless of
    the result of gst_dfbvideosink_get_best_vmode(), since the two are
    unrelated.
* Disable DirectFB signal handler
  - "--dfb:no-sighandler" option is passed to DirectFBInit().
    This prevents DirectFB from trying to kill the process and allows
    GStreamer's termination sequence to proceed normally.
