Implement two workarounds:

1) Swap U and V planes to VdpVideoSurfacePutBitsYCbCr to fix blue-tinged
   videos.

2) Disable VdpPresentationQueueSetBackgroundColor, so that Flash doesn't
   set the background to pure black or pure white, which would cause the
   VDPAU image to bleed through to other parts of the desktop with those
   very common colors.

These workarounds are only enabled when running under Flash player, and
may be individually controlled via /etc/vdpau_wrapper.cfg, should they
ever need to be disabled.

Note that this code stores the VDPAU backend function pointers as global
variables, which is technically incorrect. However, the likelihood of
any known VDPAU implementation ever returning different values for these
pointers within a single process is zero. If this becomes a problem, a
hash table of VdpDevice to the stored pointers should be implemented.
