This patchset allows to migrate and restore (snapshot) vms with older qemu ver than current installed by setting the correct machine flag.

As a sideffect you can manually set the machine flag in config if you want (f.e. testing q35 chipset support)

This series introduces:
1.) introduces a common version_to_int sub
2.) adds an optional machine parameter to the vm conf (so someone can force a special machine type via conf)
3.) save qemuver on a fresh start and set machine flag based on the qemuver
