[PATCH v4 0/4] Enable vhost-user to be used on BSD systems

[Sergio Lopez <slp@redhat.com>]

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