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.
