ce1144960c conf: change virNWFilterBindingPtr to virNWFilterBindingDefPtr
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.

15f9db5303 conf: Tweak HPT feature parsing and formatting
This doesn't seem very useful at the moment, but it will make
sense once we introduce another HPT-related setting.

The output XML is decoupled from the input XML in preparation
of future changes as well; while doing so, we can shave a few
lines off the latter.

This commit is best viewed with 'git show -w'.

Some documentation recommends to use "none" when you don't have a

f92d164c13 qemu: fix msg could be a wild pointer in qemuMonitorIOProcess()
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.

c92b6023e8 vmx: allow an odd number of vCPUs
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-May/msg02159.html
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.

205462b60b hyperv: erase "generated files" sentinel during make maintainer-clean
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
understand they need regeneration.

0c4408c832 qemu: Don't use asyncJob after stop during snapshot revert
https://bugzilla.redhat.com/show_bug.cgi?id=1591628

Attempting to use the FORCE flag for snapshot-revert was resulting
in failures because qemuProcessStart and qemuProcessStartCPUs were
using QEMU_ASYNC_JOB_START after a qemuProcessStop resulting in an
error when entering the monitor:

error: internal error: unexpected async job 6 type expected 0

So create a local @jobType, initialize to QEMU_ASYNC_JOB_START, and
change to QEMU_ASYNC_JOB_NONE if we end up in the --force path
where the qemuProcessStop is run before a Start and StartCPUs.
