redPanther f1a4672a93 Amlogic box uses aml and fb buffer (#141)
* v4l: fix auto mode opens usable device twice

* on amlogic system, start framegrabber and amlogic grabber

* tune code formating

* make aml grabber always one prio below fb

* hyperiond refactoring

* refactor hyperiond grabber donfig code
add json clinet view of active and inactive input sources
