  stm class: dummy_stm: Add link callback for fault injection (2016-02-15 15:54:37 +0200)

----------------------------------------------------------------
These are:

 * fixes for races around linking stm source devices to stm devices,
   stm output assignment, module/device refcounting;
 * random trivial fixes and cleanups;
 * a new stm source "heartbeat" device;
 * better support for multiple stm devices;
 * various small improvements.
