Add "xenlogd", a new logging daemon meant to support infrastructure
domains (e.g. xenstore-stubdom) to write log files in dom0.
As I understand it, your new daemon is a generic 9pfs backend, which
you use for logging. I think naming it something like xen9pfsd would
more accurately describe its functionality.
Fine with me. I'll wait a little bit to see what others think.
For now only add the code needed for starting the daemon and
registering it with Xenstore via a new "/tool/xenlog/state" node by
writing the "running" state to it.
To support driver domain use cases, I think you want to use a relative
Xenstore path. While this daemon is independent from libxl, it might
be easiest to use "libxl/xenlog/" ("libxl/xen9pfs/") to take advantage
of driver domains having a read-write "libxl/" directory.
You have a point here. And as it is libxl controlling the start of the
daemon, putting it under "libxl" is fine IMO.

The code looks good to me.
Thanks,
