[0/2] Enable vhost-user to be used on BSD systems

Message

Since QEMU is already able to emulate ioeventfd using pipefd, we're already
pretty close to supporting vhost-user on non-Linux systems.

This two patches bridge the gap by:

1. Extending event_notifier_get_fd() to be able to return wfd when needed.

2. Modifying the build system to it allows enabling vhost-user on BSD.

Sergio Lopez (2):
  Allow returning EventNotifier's wfd
  Allow building vhost-user in BSD
