Francesco Mazzoli 487bb77623 Notify on UNAVAIL statechange 
`UNAVAIL` is maybe not quite as concerning as `DEGRADED`, but still an
event of notice, in my opinion. For example it is triggered when a
drive goes missing.

README 

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.
