"This bit offset is the offset within the RBSP data for the slice, relative
to the starting position of the slice_header() in the RBSP"

This should fix a segfault, also it might be faster on systems where the
+52 wasnt free.

It allows VLD H264 decoding using DXVA2 (GPU assisted decoding API under
VISTA and Windows 7).
It is implemented by using AVHWAccel API. It has been tested successfully
for some time in VLC using an nvidia card on Windows 7.
To compile it, you need to have the system header dxva2api.h (either from
microsoft or using http://downloads.videolan.org/pub/videolan/testing/contrib/dxva2api.h)
The generated libavcodec.dll does not depend directly on any new lib as
the necessary objects are given by the application using FFmpeg.
