Changes:
1) D is no longer specifying the number of satip device, but disable detection of DVB devices (like /dev/dvb/adapterX/frontendY).
if -D is used, minisatip can be used only as satip client/server
2) --nopm changed to --adapter-timeout. While nopm allowed specifying which adapters to not be closed after timeout, --adapter-timeout specifies the timeout for closing the adapter. Timeout of 0 behaves exactly as --nopm.
3) connection to DVBAPI server is open only when needed instead of always on
