libcamera: Add debug printouts
Add a few debug printouts that help follow the library intialization process: what pipeline handlers are registered, what media devices are created, and which pipeline manager gets matches with the current system. The resulting output is the following, on IPU3 devices: DBG pipeline_handler.cpp:119 Pipeline handler: "PipeHandlerVimc" registered DBG pipeline_handler.cpp:119 Pipeline handler: "PipelineHandlerIPU3" registered DBG device_enumerator.cpp:214 New media device: ipu3-imgu created from: /dev/media0 DBG device_enumerator.cpp:214 New media device: ipu3-cio2 created from: /dev/media1 DBG device_enumerator.cpp:255 Succesfull match for media device: ipu3-cio2 DBG device_enumerator.cpp:255 Succesfull match for media device: ipu3-imgu DBG pipeline_handler.cpp:150 Pipeline handler: "PipelineHandlerIPU3" matched Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Jacopo Mondi <jacopo@jmondi.org>
