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. Adding a new event_notifier_get_wfd() to return wfd on the places where
the peer is expected to write to the notifier.
2. Modifying the build system to it allows enabling vhost-user on BSD.
v1->v2:
- Drop: "Allow returning EventNotifier's wfd" (Alex Williamson)
- Add: "event_notifier: add event_notifier_get_wfd()" (Alex Williamson)
- Add: "vhost: use wfd on functions setting vring call fd"
- Rename: "Allow building vhost-user in BSD" to "configure, meson: allow
enabling vhost-user on all POSIX systems"
- Instead of making possible enabling vhost-user on Linux and BSD systems,
allow enabling it on all non-Windows platforms. (Paolo Bonzini)
v2->v3:
- Add a section to docs/interop/vhost-user.rst explaining how vhost-user
is supported on non-Linux platforms. (Stefan Hajnoczi)
v3->v4:
- Some documentation fixes. (Stefan Hajnoczi)
- Pick up Reviewed-by tags.
