With this patch, the loader installs an optional client-provided fault handler as default CPU exception handler and RM fault handler for all CPU and RM sessions of the loaded subsystem. This way, loader clients become able to respond to failures occuring within the subsystem. The new feature is provided via the added 'Loader::fault_handler' RPC function. The 'run/failsafe' test covers two cases related to the loader, which are faults produced by the immediate child of the loader and faults produced by indirect children.
