e8c2c8bd07 qemu_command: Prefer '-overcommit mem-lock' over -realtime mlock'
The latter is deprecated and will be removed soon. The advised
replacement is '-overcommit mem-lock=on|off'.

75a9169881 qemu: command: Override HOME variable for system QEMU
By default, qemu user's home dir points to '/' which shouldn't be used
at all. We therefore pass the HOME variable from the current variable
iff not running as SUID, which means that for systemd we never set it.
This patch makes sure, that for system QEMU this is always set to
libDir/<driver>, session mode is left untouched.

7e73137495 qemu: command: Enforce setting XDG variables for system QEMU
For session mode, only XDG_CACHE_HOME is set, because we want to remain
integrating with services in user session, but for system mode, this
would have become reading/writing to '/' which carries the obvious issue
with permissions (also, '/' is the wrong location in 99.9% cases anyway).

d60c17b3d7 tests: Remove disk from 'serial-unix-chardev' test
We are testing character devices so the disk is not necessary. Minimize
the configuration. This will prevent changes when switching to blockdev.

1bc1a7e320 qemu: fix UNIX socket chardevs operating in client mode
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.
