Bug #58426 Crashing tests not failing as they are supposed to on Solaris 10 debug

Browse Source 
On this platform we seem to get lots of other signals
while waiting for SIGKILL to be delivered.

Solution: use sigsuspend(<all signals blocked>)



dbug/dbug.c:
  New function _db_suicide_() which does kill(myself, -9) and then waits forever.
include/my_dbug.h:
  Let DBUG_SUICE wait forever until the KILL signal is delivered, and process dies.
