Add "xen-9pfsd", a new logging daemon meant to support infrastructure
domains (e.g. xenstore-stubdom) to access files in dom0.

For now only add the code needed for starting the daemon and
registering it with Xenstore via a new "libxl/xen-9pfs/state" node by
writing the "running" state to it.

'_' is much less common in xenstore node names than '-'.  Is there a
particular reason you chose '_'?  I generally prefer '-', but IIRC the
libxl idl can't handle '-'.  Did you hit that?

Yes.
