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. Only change in this revision is removing mistakenly added temporary file in patch 3.
