[PATCH v9 0/6] tools: enable xenstore-stubdom to use 9pfs

[Juergen Gross <jgross@xxxxxxxx>]

This series is adding 9pfs support to Xenstore-stubdom, enabling it
to do logging to a dom0 directory.

This is a prerequisite for the final goal to add live update support
to Xenstore-stubdom, as it enables the stubdom to store its state in
a dom0 file.
