vhost-user-fs: handle FS_IO request

Browse Source 
Virtiofs's dax window can be used as read/write's source (e.g. mmap a file
on virtiofs), but the dax window area is not shared with vhost-user
backend, i.e. virtiofs daemon.

To make those IO work, addresses of this kind of IO source are routed to
VMM via FS_IO requests to perform a read/write from an fd directly to the
given GPA.

This adds the support of FS_IO request to clh's vhost-user-fs master part.
