[PATCH 1/4] libxl: honor domain lifecycle event configuration

[Jim Fehlig <jfehlig@xxxxxxxx>]

The libxl driver was ignoring the <on_*> domain event configuration,
causing e.g. a domain to be rebooted even when on_reboot is set to
destroy.

This patch honors the <on_*> configuration in the shutdown event
handler.
