This series of patches implements the control_message interface to
enable programmatic control (through the API) of the capture state
(start/stop) of a dshow device, and allows to pop up its configuration
dialogs through the API. For this, the control_message needes to be
implemented for a AVInputFormat, since it was only available for a
AVOutputFormat. Furthermore a new value was added to the
AVAppToDevMessageType enum.
Note that i was not able to test the last patch in this series myself
as I do not have access to the devices it affects. I expect no big
trouble because for code that concerns these devices, I only moved
some of it into functions, didn't change its logic. Rest is thoroughly
tested of course.

Diederick Niehorster (6):
  avformat: add control_message function to AVInputFormat
  avdevice/dshow: implement control_message interface
  avdevice: adding control message requesting to show config dialog
  avdevice/dshow: accept show config dialog control message
  avdevice/dshow: tv_tuner_audio_dialog cleanup missing
  avdevice/dshow: add config dialog command for crossbar and tv tuner
