[PATCH 2/3] xl: introduce a function to get shutdown action name

[Wei Liu <wei.liu2@citrix.com>]

The array to map libxl_shutdown_action_to_shutdown to string is going to
be moved to a dedicated file.

Provide a function to do the translation so that we don't need to make
the array globally visible.
