vdpau: Improve detection of supported files.

A minor improvement on the detection of whether or not a video will
play. It is a good idea to at least make sure that the video codec
is supported and that the resolution does not exceed the supported
resolution.

Reduce the amount of false positives while detecting stereo mode

Initially the CStereoscopicsManager::DetectStereoModeByString
function considered file names containing strings like " SBS "
to be 3D content. However, it turned out this also caused false
positives, for example when opening PVR recordings from the
Dutch TV channel "SBS 6".

Reduced the amount of false positives by also searching for
the keyword "3D" in the file name before considering a file
to be 3D content and by using regular expressions

vdpau fixes
Added some vc_tv_* functions that were missing in DllBCM.
Moved private utility functions to end of file, and added declarations at the top.
Added private utility function to map a float display aspect, to the respective SDTV_ASPECT_* enum value.
Changed SDTV resolutions to be treated similarly to HDMI resolutions in SetNativeResolution. This means that the SDTV interface is powered up and set to the right mode.
