patch for h264parse to evaluate vui parameters only when they where parsed and
set

Testpipeline:

GST_DEBUG=h264*:5 gst-launch filesrc location=test.mpg  ! mpegpsdemux !
h264parse ! fakesink 2>&1 | grep ratio

0:00:00.447200775  1381    0x8d200 INFO               h264parse
gsth264parse.c:1070:gst_h264_parse_update_src_caps:<h264parse0> aspect ratio
idc changed 144
0:00:00.901053845  1381    0x8d200 INFO               h264parse
gsth264parse.c:1070:gst_h264_parse_update_src_caps:<h264parse0> aspect ratio
idc changed 145
....

The Problem is evaluation of vui_parameters which are not set or not parsed
(and so h264pase compares uninitialized memory)....
