  This series aims at improving the Vhost FD manager.
The fdset internals is hidden from its callers, the
notification/synchronization is made systematic for
every FD add/del operations and finally the code is
reworked to make use of epoll insteal of poll which
reduces the complexity (less locks involved,
synchrnoization no more necessary).

The series has been tested with both Vhost-user/Virtio-user
and with VDUSE.
