OpenZFS-issue: https://www.illumos.org/issues/5997
OpenZFS-commit: https://github.com/openzfs/openzfs/commit/1437283

Porting Notes:

In addition to the OpenZFS changes this patch realigns the events
with those found in OpenZFS.

Events which would be logged as sysevents on illumos have been
been mapped to the 'sysevent' class for Linux.  In addition, several
subclass names have been changed to match what is used in OpenZFS.
In all cases this means a '.' was changed to an '_' in the subclass.

The scripts provided by ZoL have been updated, however users which
provide scripts for any of the following events will need to rename
them based on the new subclass names.
