Mirror and migration use dirty bitmaps for their purposes, and since commit [block: per caller dirty bitmap] they use their own bitmaps, not the global one. But they use old functions bdrv_set_dirty and bdrv_reset_dirty, which change all dirty bitmaps. Named dirty bitmaps series by Fam and Snow are affected: mirroring and migration will spoil all (not related to this mirroring or migration) named dirty bitmaps. This patch fixes this by adding bdrv_set_dirty_bitmap and bdrv_reset_dirty_bitmap, which change concrete bitmap. Also, to prevent such mistakes in future, old functions bdrv_(set,reset)_dirty are made static, for internal block usage.
