Original commit message from CVS: * po/POTFILES.in: add dvbsrc * sys/dvb/gstdvbsrc.c: (gst_dvbsrc_class_init), (gst_dvbsrc_init), (gst_dvbsrc_set_property), (gst_dvbsrc_get_property), (gst_dvbsrc_open_frontend), (gst_dvbsrc_open_dvr), (gst_dvbsrc_finalize), (read_device), (gst_dvbsrc_create), (gst_dvbsrc_start), (gst_dvbsrc_frontend_status), (gst_dvbsrc_tune), (gst_dvbsrc_unset_pes_filters), (gst_dvbsrc_set_pes_filter): * sys/dvb/gstdvbsrc.h: adapter-prefix is a terrible name for a device, so replace it. strerror should be used immediately after the syscall related to it. Actually throw a reasonable GST_ELEMENT_ERROR if we fail to open (pretty easy to trigger by opening the same device twice). Use _OBJECT macros where it makes sense. This element is going to need some work before it moves.
