  VAAPI: Rework driver workarounds

- NV12 definitely seems the best supported format across different GPUs
(and is by all accounts the preferred internal format)
- Ironlake still returns corrupt frames for I420 and MPEG2 however...

  MythRenderOpenGL: Reinstate limited rectangular texture support

- there's always an exception. In this case OSX IOSurface to texture
mapping (for zero copy VideoToolBox rendering) requires rectangular
textures.
- support is limited, is treated as the exception and is only available
for 'external' textures that are manually created and passed into
OpenGLVideo.
