d1ac8e1034 CrystalHD: Improve detection of field pair -> two fields content. 
Istvan Sebok provided a sample where field pair -> two fields content
was being misdetected by the existing logic. I added an additional
test to check the input picture type as identified by our h.264
parser.

It is no longer used anywhere.

Furthermore, the header it was declared in was not installed,
so it can not be considered part of the public API.
