  Fix drm format and modifier handling
  
  Move functions to private
  Change case on methods to lowercase per style guide
  Change related methods to use set instead of vector,
  this saves a copy from set to vector.
  Initialize formats before supportsDmaBufFormat because
  queryDmaBufModifiers can be called before queryDmaBufFormats
  and need to initialize at supportsDmaBufFormats.
