In order to learn what types of <launchSecurity/> are supported
users can turn to domain capabilities and find <sev/> and
<s390-pv/> elements. While these may expose some additional info
on individual launchSecurity types, we are lacking clean
enumeration (like we do for say device models). And given that
SEV and SEV SNP share the same basis (info found under <sev/> is
applicable to SEV SNP too) we have no other way to report SEV SNP
support.
Therefore, report supported launchSecurity types in domain
capabilities.

The virNetworkObjSetFwRemoval() function is called at least two

initializes:
1) when loading state XMLs:

2) when firewall rules are being reloaded:

Commit v10.0.0-265-ge67bca23e4 added a `active_config` and
`defined_config` to nodedev mdev internal XML handling.
`defined_config` can be filled at XML parse time, but `active_config`
must be filled in by nodedev driver. This wasn't implemented for the
test driver however, which caused virt-manager test suite regressions.
Working example:
```
$ virsh --connect test:///home/crobinso/src/virt-manager/tests/data/testdriver/testdriver.xml nodedev-dumpxml mdev_8e37ee90_2b51_45e3_9b25_bf8283c03110

<capability type='mdev'>

There are PCI devices with pretty large non-prefetchable memory,
for instance:
Memory at 9d800000 (64-bit, non-prefetchable) [size=8M]
Memory at a6800000 (64-bit, non-prefetchable) [size=16K]
For cold plugged devices this is not a problem, because firmware
sets PCI controllers in a way that make devices behind them just
work. Problem arises if such PCI device is to be hot plugged.
Since the PCI device wasn't present at cold boot, firmware could
not take it into calculations and the amount of reserved memory
is not sufficient.
Introduce a know that allows users overriding value computed by
FW and thus allow hot plug of such PCI devices.

As of v9.8.0-rc1~7 we check whether two <memory/> devices don't
overlap (since we allow setting where a <memory/> device should
be mapped to). We do this pretty straightforward, by comparing
start and end address of each <memory/> device combination.
But since only the start address is given (an exposed in the
XML), the end address is computed trivially as:
start + mem->size * 1024
And for majority of memory device types this works. Except for
NVDIMMs. For them the <memory/> device consists of two separate
regions: 1) actual memory device, and 2) label.
Label is where NVDIMM stores some additional information like
namespaces partition and so on. But it's not mapped into the
guest the same way as actual memory device. In fact, mem->size is
a sum of both actual memory device and label sizes. And to make
things a bit worse, both sizes are subject to alignment (either
the alignsize value specified in XML, or system page size if not
specified in XML).
Therefore, to get the size of actual memory device we need to
take mem->size and substract label size rounded up to alignment.
If we don't do this we report there's an overlap between two
NVDIMMs even when in reality there's none.
