Initial implementation of zed (ZFS Event Daemon) zed monitors ZFS events. When a zevent is posted, zed will run any scripts that have been enabled for the corresponding zevent class. Multiple scripts may be invoked for a given zevent. The zevent nvpairs are passed to the scripts as environment variables. Events are processed synchronously by the single thread, and there is no maximum timeout for script execution. Consequently, a misbehaving script can delay (or forever block) the processing of subsequent zevents. Plans are to address this in future commits. Initial scripts have been developed to log events to syslog and send email in response to checksum/data/io errors and resilver.finish/scrub.finish events. By default, email will only be sent if the ZED_EMAIL variable is configured in zed.rc (which is serving as a config file of sorts until a proper configuration file is implemented).

Cleanup ZEDLETs This commit factors out several common ZEDLET code blocks into zed-functions.sh. This shortens the length of the scripts, thereby (hopefully) making them easier to understand and maintain. In addition, this commit revamps the coding style used by the scripts to be more consistent and (again, hopefully) maintainable. It now mostly follows the Google Shell Style Guide. I've tried to assimilate the following resources: Google Shell Style Guide https://google-styleguide.googlecode.com/svn/trunk/shell.xml Dash as /bin/sh https://wiki.ubuntu.com/DashAsBinSh Filenames and Pathnames in Shell: How to do it Correctly http://www.dwheeler.com/essays/filenames-in-shell.html Common shell script mistakes http://www.pixelbeat.org/programming/shell_script_mistakes.html Finally, this commit updates the exit codes used by the ZEDLETs to be more consistent with one another. All scripts run cleanly through ShellCheck <http://www.shellcheck.net/>. All scripts have been tested on bash and dash.
