V4L/DVB (11782): Siano: smsdvb - use 'push' status mechanism
This patch replace the old method of pulling the device status by sending "get_statistics" request, to push mode. This make status update much faster, and reduce various operation time (UHF scan now takes 15s instead of 2m). In order to make the change the following modification have been applied: 1) core header - update statistics headers. 2) dvb adapter - omit the statistics request, add handling of status indications. 3) core 'onresponse' - re-route messages addressed to other adapter to the dvb adapter.
