We are going to want to expose the NWFilter binding concept in the
public API, so the virNWFilterBindingPtr type needs to be used there.
Our internal type will shortly gain an XML representation, so rename
it to virNWFilterBindingDefPtr which follows our normal conventions.

The output XML is decoupled from the input XML in preparation

As qemuMonitorJSONIOProcess will call qemuMonitorJSONIOProcessEvent
which unlocks the monitor mutex, there is some extreme situation,
eg qemu send message to monitor twice in a short time, where the
local viriable 'msg' of qemuMonitorIOProcess could be a wild point:

1. qemuMonitorSend() assign mon->msg to parameter 'msg', which is alse a
local variable of its caller qemuMonitorJSONCommandWithFd(), cause
eventloop to send message to monitor, then wait condition.
2. qemu send message to monitor for the first time immediately.
3. qemuMonitorIOProcess() is called, then wake up the qemuMonitorSend()
thread, but the qemuMonitorSend() thread stuck for a while as cpu pressure
or some other reasons, which means the qemu monitor is still unlocked.
4. qemu send event message to monitor for the second time,
such as RTC_CHANGE event
5. qemuMonitorIOProcess() is called again, the local viriable 'msg' is
assigned to mon->msg.
6. qemuMonitorIOProcess() call qemuMonitorJSONIOProcess() to deal with
the qemu event.
7. qemuMonitorJSONIOProcess() unlock the qemu monitor in the macro
'QEMU_MONITOR_CALLBACK', then qemuMonitorSend() thread get the mutex
and free the mon->msg, assign mon->msg to NULL.

Most probably this was a limitation in older ESX versions, and it seems
it does not exist anymore in more recent versions; see the following
thread:

https://www.redhat.com/archives/libvir-list/2018-June/msg00043.html

Hence, allow an odd number (greater than 1) of vCPUs, since most
probably older versions of ESXi will error out anyway.

Re-generating of generated source files in the hyperv directory
depends on src/.hyperv_wmi_generator.stamp not existing, or having a
timestamp older than src/hyperv/hyperv_wmi_generator.py. "make
maintainer-clean" erases the generated files, but not this sentinel
file, so the erased files aren't regenerated during the next
make. Once we add it to the list of MAINTAINERCLEANFILES, it gets
deleted at the same time as the generated files, so make is able to

in failures because qemuProcessStart and qemuProcessStartCPUs were

So create a local @jobType, initialize to QEMU_ASYNC_JOB_START, and
