[PATCH v3 0/3] MR1003: gdiplus: Use atomic write for releasing GpImage lock.

[Jinoh Kang (＠iamahuman)]

This fixes data race in ARM/ARM64 platforms, and prevents potential
memory access reordering by the compiler.

--
  v3: gdiplus: Replace GpImage's busy flag with SRWLOCK.
      gdiplus: Avoid copying GpImage's busy flag in select_frame_wic().
      gdiplus: Avoid recursively locking image in GdipImageRotateFlip.
