Introduce functions to read and write the state of the VM in xenstore.

This basically creates a new management interface for QEMU via the

Our management interface is QMP. If you want to maintain compatibility,
you'll need to write a QMP ->  xenstore daemon that maps events

This would belong in xl/libxl.

Yes, but considering that we don't want a xenstore-based management
interface I would gladly do without the compatibility daemon.
We'll try to reduce all the xenstore interaction to the bare minimum,
and use QMP everywhere else.

Yes, I was just pointing out that you don't need a new compatibility daemon. Since xl is already daemonizing itself to handle on_crash and friends, it could also set up all the watches it cares about, and convert them to QMP commands. It's all more code that needs to be written of course, and boring stuff even. :)
