This patch introduces new attribute to filesystem element
to support customizable access mode for mount type.
Valid accessmode are: passthrough, mapped and squash.

   if non-NULL this was never freed because of a missing
     VIR_FREE(accessmode);
in the clanup: section of that routine.


   otherwise, ACK. I was just a bit worried that if no model was given
we always assume passthrough, but since that's what the QEMu backend
implementation did so far and this doesn't affect other drivers, that's
fine.

   Applied and pushed with that small change,

    thanks !

Thanks very much ! :)
