This should be faster (couldnt meassue a difference), and its less picky
on slightly out of spec dquant.

The various avcodec_thread_init() functions are updated to return
immediately after setting avctx->thread_count.  This allows -threads 0
to pass through to codecs.  It also simplifies the usage for apps
using libavcodec.

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.

This obscure macro is only used in motion_est.c so having it in lavc
makes more sense.  See discussion here:

With b_keyframe instead of IDR for detecting keyframes, ffmpeg should now
support periodic encoding with periodic intra refresh (although there is no
interface option for it yet).
Set the new timebase values for full VFR input support.
Bump configure to check for API version 83.
