Log:

Windows: Add DXVA2 hardware decoding support.

- You will need to download the dxva2api.h from the VLC website, install it in an appropriate include path and re-run configure with --enable-dxva2
- Enable Windows Hardware Acceleration decoder support in the display profile of your choice.
- This is alpha quality at best and this version has only been tested on Vista with an NVidia 9400M chipset (MacBook in bootcamp).
- There is no deinterlacing or other video processing support at this time.
- It is largely stable with MPEG2, H.264 and VC1 support all working though there will be fixes required for certain chipsets and codecs (just as for VDPAU).
- Most stability issues appear to be unrelated to DXVA2 and are general issues with this windows build.

- There is significant picture breakup when starting playback and occasional glitches at other times.

If you are going to test (especially if using the new windows build script), please compile a debug build so we can iron out all of the outstanding issues as quickly as possible.
