[libvirt] [PATCH v5 11/36] qemu_process: Collect monitor code in single function
qemuMonitor code lives in qemuProcessQmpConnectMonitor rather than in
qemuProcessQmpNew and qemuProcessQmpLaunch.
This is consistent with existing structure in qemu_process.c where
qemuConnectMonitor function contains monitor code for domain process
activation.
Simple code moves in this patch. Improvements in later patch.
Only intended functional change in this patch is we don't
move (include) code to initiate process stop on failure to create monitor.
As comments in qemuProcessQmpStart say... Client must always call
qemuProcessStop and qemuProcessQmpFree, even in error cases.
