Paolo Bonzini c27025e044 runstate: cleanup reboot and panic actions
The possible choices for panic, reset and watchdog actions are inconsistent.

"-action panic=poweroff" should be renamed to "-action panic=shutdown"
on the command line.  This is because "-action panic=poweroff" and
"-action watchdog=poweroff" have slightly different semantics, the first
does an unorderly exit while the second goes through qemu_cleanup().  With
this change, -no-shutdown would not have to change "-action panic=pause"
"pause", just like it does not have to change the reset action.

"-action reboot=none" should be renamed to "-action reboot=reset".
This should be self explanatory, since for example "-action panic=none"
lets the guest proceed without taking any action.
