base with 2e9e8b5 dvb: Use DVB_API_VERSION to know if we have recent enough
version

I saw the segfault with some test stream.
This test stream has no "vps_sub_layer_ordering_info_present_flag".
and The gsth265parser.c:1756 and gsth265parser.c:1927 is some problem.

-----------------------------------------------------------
for (i = 0; i <= (vps->max_sub_layers_minus1 - 1); i++) {

if vps->max_sub_layers_minus1 is zero , then (vps->max_sub_layers_minus1-1) is
0xFFFF. 

-----------------------------------------------------------

so I fixed this problem. Could you check it?
