zed syslog entries drop important info
ZED will log zevents summaries to the syslog, however the log entries 
tend to drop event details that can be useful for diagnosis. This is 
especially true for ereport events, like io, checksum, and delay.

Update the all-syslog.sh script to log additional event information.

Add an optional config option, ZED_SYSLOG_DISPLAY_GUIDS, to zed.rc
for choosing GUIDs over names for pool and vdev.

Change the default ZED_SYSLOG_SUBCLASS_EXCLUDE to exclude history_event 
events. These events tend to be frequent, convey no meaningful info, 
and are already logged in the zpool history.

Shell scripts are the recommended choice for ZEDLETs that mostly call
other utilities and do relatively little data manipulation.

Shell scripts MUST work on both bash and dash.

Shell scripts MUST run cleanly through ShellCheck:
  http://www.shellcheck.net/

General functions reside in "zed-functions.sh".  Use them where applicable.
