MFV r319737: 6939 add sysevents to zfs core for commands

Browse Source 
illumos/illumos-gate@ce1577b049
ce1577b049

https://www.illumos.org/issues/6939
  Originally created https://smartos.org/bugview/OS-4489
       sysevents should be fired in the kernel from ZFS whenever a command
       is run that is logged in zpool history.
  Example output
  Terminal 1
  root - gz sunos ~ # zfs create zones/foobar
  root - gz sunos ~ # zfs set quota=10g zones/foobar
  root - gz sunos ~ # zfs destroy zones/foobar
  Terminal 2
  root - gz sunos ~ # sysevent EC_zfs
  nvlist version: 0

      class = EC_zfs
      subclass = ESC_ZFS_history_event
