[Qemu-devel] [PATCH v5 0/9]: Introduce the RunState type

[Luiz Capitulino]

It replaces the VMSTOP macros and allows us to drop some global variables.

Additionally, the problem with issuing 'cont' when the VM is in bad state
is addressed and we make the current state available in QMP and HMP.

** IMPORTANT: patch 04/09 is a new addition, it needs careful review.

This is breaking every few days due to changes in master, let's try to
review and merge it ASAP.
