Subject: [PATCH] qemu: fix UNIX socket chardevs operating in client mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When support was adding for passing a pre-opened listener socket to UNIX
chardevs, it accidentally passed the listener socket for client mode
chardevs too with predictable amounts of fail resulting. This affects
libvirt when using QEMU >= 2.12
Expand the unit test coverage to validate that we are only doing FD
passing when operating in server mode.
