17b4734288 schema: allow a <rule> element with no subelements in a nwfilter
This is a regression in behavior caused by commit 37359814. It was
intended to limit the schema to allow only a single subelement of
<rule>, but it is also acceptable for <rule> to have no subelement at
all.

To prevent the same error from reoccurring in the future, the
examples/xml/nwfilter directory was added to the list of nwfilter
schema test directories.

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.

14781dcde6 qemu_command: replace vlan= with netdev= for legacy nic
VMs with hardcoded platform network devices are forced to use old
style '-net nic' command line config. Current we use qemu's vlan
option to hook this with the '-netdev' host side of things.

However since qemu 1.2 there is '-net nic,netdev=X' option for
explicitly referencing a netdev ID, which is more inline with
typical VM commandlines, so let's switch to that
