  Skip Texture::syncState when no dirty bits.
  
  We sometimes generate local dirty bits in TextureGL. To make sure the local
  dirty bits don't get skipped we use a Subject/Observer pattern between the
  TextureGL and gl::Texture. This allows us to skip syncState in the hot path.
  
  Also inlines a couple of other texture functions. And fixes a stray header
  in EGLBlobCacheTest.
