There are various allocations that can't be moved or shrunk. Provide a global callback struct for this use case instead of making each caller declare its own dummy struct. Also fixed ROLO and x1000 installer code which incorrectly used movable allocations. Change-Id: I00088396b9826e02e69a4a33477fe1a7816374f1
