v2:
- Replaced the individual qmp commands in patch 3/4 for a generic set-action
command that takes a RunStateAction parameter, specifying an event|action pair.
- Removed qmp_ prefix from X_set_action() functions in runstate-action.c

***

This is a follow up to the proposal to add a "-no-panicstop" option to QEMU that would allow us to
control whether the VM is paused or allowed to continue running without intervention from a management layer
when a guest panic occurs. See the inital thread and replies for details:

https://lore.kernel.org/qemu-devel/1601606494-1154-1-git-send-email-alejandro.j.jimenez@oracle.com/

From that discussion came a request for a generic mechanism to group options like -no-shutdown, -no-reboot, etc,
that specify an action taken by QEMU in response to a guest event (reboot, shutdown, panic, and watchdog
expiration are the current options). The existing options would translate to the new option, like:

* -no-reboot --> "-action reboot=shutdown"
* -no-shutdown --> "-action shutdown=pause"

Please share any questions or comments.

Regards,
Alejandro
