34204f9923 scripts: fix tokenizing of enum parameters in API builder
The API build script tokenizes enums declarations by first splitting on
whitespace. This is unhelpful as it means an enum

 # define VIR_USE_CPU(cpumap, cpu) ((cpumap)[(cpu) / 8] |= (1 << ((cpu) % 8)))

Gets tokenized as

  #define
  VIR_USE_CPU(cpumap,
  cpu)
  ((cpumap)[(cpu)
  /
  8]
  |=
  (1
  <<
  ((cpu)
  %
  8)))

With this change, the set of parameters are all merged into the first
token:

  #define
  VIR_USE_CPU(cpumap,cpu)
  ((cpumap)[(cpu)
  /
  8]
  |=
  (1
  <<
  ((cpu)
  %
  8)))

which is more convenient to process later on in the script.

69daa2ea8a testCompareXMLToArgvValidateSchema: Construct @vm from scratch
Currently, the @vm is passed in as an argument and
testCompareXMLToArgvCreateArgs() is called over it which means
under the hood qemuProcessPrepareDomain() is called. But at the
point where ValidateSchema() is called, the domain object is
already 'prepared', i.e. all device aliases are assigned and so
on. But our code is not prepared to 'prepare' a domain twice - it
simply overwrites all the pointers leading to a memory leak.

Fortunately, this is only the problem of this test.

Resolve this by constructing the domain object from scratch.

Use all the the input data to also validate the arguments for -netdev

78d30aa0bf qemu: Prepare for testing of 'netdev_add' props via qemuxml2argvtest
qemuxml2argv test suite is way more comprehensive than the hotplug
suite. Since we share the code paths for monitor and command line
hotplug we can easily test the properties of devices against the QAPI
schema.

To achieve this we'll need to skip the JSON->commandline conversion for
the test run so that we can analyze the pure properties. This patch adds
flags for the comand line generator and hook them into the
JSON->commandline convertor for -netdev. An upcoming patch will make use
of this new infrastructure.

about adding another object for it. Either way it requires us to add yet

b6738ffc9f qemu: command: Generate -netdev command line via JSON->cmdline conversion
The 'netdev_add' command was recently formally described in qemu via the
QMP schema. This means that it also requires the arguments to be
properly formatted. Our current approach is to generate the command line
and then use qemuMonitorJSONKeywordStringToJSON to get the JSON
properties for the monitor. This will not work if we need to pass some
fields as numbers or booleans.

In this step we re-do internals of qemuBuildHostNetStr to format a JSON
object which is converted back via virQEMUBuildNetdevCommandlineFromJSON
to the equivalent command line. This will later allow fixing of the
monitor code to use the JSON object directly rather than rely on the
conversion.

c0e04c2e62 qemu: prevent attempts to detach a device on a controller with hotplug='off'
Although the original patches to support controllers with
hotplug='off' were checking during hotplug/attach requests that the
device was being plugged into a PCI controller that didn't have
hotplug disabled, but I forgot to do the same for device detach (the
main impetus for adding the feature was to prevent unplugs originating
from within the guest, so it slipped my mind). So although the guest
OS was ultimately unable to honor the unplug request, libvirt could
still be used to make such a request, and since device attach/detach
are asynchronous operations, the caller to libvirt would receive a
success status back (the device would stubbornly/correctly remain in
the domain status XML however)

This patch remedies that, by looking at the controller for the device
in the detach request, and immediately failing the operation if that
controller has hotplug=off.

8fd2749b2d qemuProcessStop: Reattach NVMe disks a domain is mirroring into
If the mirror destination is not a file but a NVMe disk, then
call qemuHostdevReAttachOneNVMeDisk() to reattach the NVMe back
to the host.

This would be done by blockjob code when the job finishes, but in
this case the job won't finish - QEMU is killed meanwhile.
