Merge tag 'pull-request-2023-05-26' of https://gitlab.com/thuth/qemu into staging

* Use MachineClass->default_nic in more machines to allow running them
  without "--nodefaults" in builds that used "--without-default-devices"
* Improve qtests for such builds
* Add up-/downsampling qtest
* Avoid crash if default RAM backend name has been stolen
* Fix reentrant DMA problem in the lsi53c895a device (CVE-2023-0330)
