Here's what I'm squashing in. The MergeBitmaps test depends on my
cleanup to use TestNewSchema everywhere. Also, I noticed that if we
wanted to use VIR_AUTOPTR(qemuMonitorTest) it might make a lot of the
file easier to read, but that should be a separate patch (including fixing:
qemumonitorjsontest.c:1431:5: error: cleanup argument not a function
VIR_AUTOPTR(qemuMonitorTest) test = NULL;
^~~~~~~~~~~
)
