vl: Add an -action option specifying response to guest events
Several command line options currently in use are meant to modify
the behavior of QEMU in response to certain guest events like:
-no-reboot, -no-shutdown, -watchdog-action.
These can be grouped into a single option of the form:
-action event=action
Which can be used to specify the existing options above in the
following format:
-action reboot=none|shutdown
-action shutdown=poweroff|pause
-action watchdog=reset|shutdown|poweroff|pause|debug|none|inject-nmi
This is done in preparation for adding yet another option of this
type, which modifies the QEMU behavior when a guest panic occurs.
