Subject: [PATCH] qemuBuildChrChardevStr: Introduce @nowait argument
RHEL-7.3: https://bugzilla.redhat.com/show_bug.cgi?id=1366108
RHEL-7.3.z: https://bugzilla.redhat.com/show_bug.cgi?id=1392032
This alone makes not much sense. But the aim is to reuse this
function in qemuBuildVhostuserCommandLine() where 'nowait' is not
supported for vhost-user devices.
Conflict: Because e3d3c04a is not backported.

(cherry picked from commit 336d4a71feb1cd68df13e1812e86971c61553522)
