c6d7b9a261 qemu: Don't use memory-backend-memfd for NVDIMMs
If guest is configured to use memfd then the function that build
memory-backend-* part of command line will put
memory-backend-memfd, always. Even for NVDIMMs. This is not
correct, because NVDIMMs need a backing path (usually to a real
host NVDIMM device). Therefore, regardless of memfd being
requested, we have to stick with memory-backend-file.

d53afa1e66 tests: qemucapabilities: Add test-data for the qemu-6.1 cycle
Add test data based on qemu commit v6.0.0-540-g6005ee07c3.

Notable changes are the removal of 'sheepdog' disk storage protocol.

Additionally the cpu model reported when probing seems to have changed
from:

"model-id": "AMD Ryzen 9 3900X 12-Core Processor            "

to:

"model-id": "QEMU TCG CPU version 2.5+"

despite building on the same machine. This probably also results in the
2 test changes in the CPU definition which popped up in this update.

virCommandToString has the possibility to return an already wrapped

The main advantage is that arguments for an option are always on the
same line which makes it more easy to see what changed in a diff and
prevents re-wrapping of the line if a wrapping point moves over the
threshold.

Additionally the used output is the same we have in the VM log file when
a VM is starting.

This is available in QEMU with "ide-hd" and "scsi-hd" device
types. It was originally mistakenly added to the "scsi-block"
device type too, but later removed. This doesn't affect libvirt
since we restrict usage to device=disk.

When this property is not set then QEMU's default behaviour
is to not report any rotation rate information, which
causes most guest OS to assume rotational storage.

which also means that we don't need to emit the empty element
<firmware type='efi'/> for all existing configs too.

511bdb0bb2 qemu: don't raise error upon interface update without <frames/> for <rx/> in coalesce
With this, incomplete XML without <frames/> for <rx/> in coalesce
won't raise error as before. It will leave the coalesce parameter
empty, thanks to passing it as a parameter and return an integer
to indicate error state - previously it returned pointer (or NULL
for both error and incomplete XML).
I also added a test case to test this functionality in the
qemuxml2xmltest.

The code went through some refactoring:
* change of a condition
* addition of a parameter
* change of order, that allowed removal of VIR_FREE
* removal of redundant labels and variables

isn't conditionally compiled in qemu.

All caps-based test now switch to using JSON for -object.
