More adventures in Software FMA

in Oracle Solaris Performance, Panics, Hangs, and Dtrace (MOSC)

Back in Oracle Solaris 11 we added the concept of Software Fault Management Architecture (SWFMA), with two types of event modelled as FMA defects. One was panic events, the other SMF service state transitions. This also allowed for notification of all FMA events via a new service facility (svccfg setnotify) over SNMP and email.

With a brief diversion to make crash dumps smaller, and faster, and easier to diagnose, we've come back to the SWFMA concept and extended it in two ways.
