Make the backend type of 9pfs PV devices configurable. The default is "qemu" with the related Xenstore backend-side directory being "9pfs". Add another type "xen_9pfsd" with the related Xenstore backend-side directory "xen_9pfs". As additional security features it is possible to specify: - "max-space" for limiting the maximum space consumed on the filesystem in MBs - "max-files" for limiting the maximum number of files in the filesystem - "max-open-files" for limiting the maximum number of concurrent open files For convenience "auto-delete" is available to let the backend delete the oldest file of the guest in case otherwise "max-space" or "max-files" would be violated. The xen-9pfsd daemon will be started by libxenlight automatically when the first "xen_9pfs" device is being created.
