Dima Dorfman 13704ca508 Introduce DEVICE_INIT, DEVICE_GET, and DEVICE_SHUTDOWN macros. As the
names suggest, they perform methods on Device's.  In addition, they
check that the pointer passed to them is valid; if it isn't, they
pretend that the action failed.  This fixes some crashes due to NULL
dereferences (e.g., PR 26509).
