David van Moolenbroek 6c7e614940 SEF: identity transfer only after controlled crash 
Transparent (endpoint-preserving) restarts with identity transfer
are meant to exercise the crash recovery system only.  After *real*
crashes, such restarts are useless at best and dangerous at worst,
because no state integrity can be guaranteed afterwards.  Thus,
except after a controlled crash, it is best not to perform such
restarts at all.  This patch changes SEF such that identity transfer
is successful only if the old process was the subject of a crash
induced through "service fi".  As a result, testrelpol.sh should
continue to be able to use identity transfers for testing purposes,
but any real crash will be handled more appropriately.

This fixes #126.
