Original commit message from CVS: * gst-libs/gst/rtp/gstbasertppayload.c: (gst_basertppayload_class_init), (gst_basertppayload_init), (gst_basertppayload_event), (gst_basertppayload_push), (gst_basertppayload_set_property), (gst_basertppayload_get_property), (gst_basertppayload_change_state): * gst-libs/gst/rtp/gstbasertppayload.h: Fix ranges of rtp payloader properties so that the full range can be used in addition to -1 (random). Fix wrong seqnum reporting in caps. Fixes #420326.
