broken when using v4l2

  MythOpenGLInterop: Refactor interop support check

- use VideoFrameType rather than MythCodecID for the check - which is a
more sensible indicator.
- ensure subclass interop checks are protected as they do not enforce
thread safety checks.
- ensure all MythCodecContext subclasses call the 'master'
MythOpenGLInterop::GetInteropType which does enforce thread safety
- cache known supported formats in MythOpenGLInterop::GetInteropType to
speed things up a little.
- ensure all subclass constructors/destructors are protected (they are
reference counted so should not be created/deleted directly)
- don't pass the MythRenderOpenGL object to the GetInteropType
implementations.
