such as virtio-mem. Allow configurations where no slots are added.

Newer GCC (13.1.1 in my case) wrongly reports "maybe uninitialized"
warning for this variable inside the next condition. Even though this
accusation is wrong (the condition is guarded by the same condition as
the for cycle initializing it), initialize it during the declaration so
compilation errors don't stop others and maybe also future proof the
code for changes.

Format the rule attributes in two passes, first for positive 'match' and

Use virXMLNodeGetSubelementList to get the elements to process.
The new approach documents the complexity of the parser, which is
designed to ignore unknown attributes and parse only a single kind of
them after finding the first valid one.
Note that the XML schema doesn't actually allow having multiple
sub-elements, but I'm not sure how that translates to actual configs
present.

We allow (some) domain devices to have a different <seclabel/>
than the top level domain one (this is mostly to allow access to
a resource for multiple domains). Now, we do couple of sanity
checks for such <seclabel/>, e.g. when the <label/> is specified,
but '@relabel' is set to no. But what we are missing is the
opposite: when '@relabel' is set, but no <label/> was provided.
Our schema already denies such combination. Make our parser
behave the same.

Both virtio-mem and virtio-pmem devices have '.memaddr' attribute
which controls the address where they are mapped in the guest
memory. Ideally, users do not need to specify this as QEMU does
the right thing and computes addresses automatically on startup.
But soon, we will need to record this address as it is part of
guest ABI. And also, there might be some users that want to
control this value. Now, we are in a bit of a pickle, because
both these device types already have a PCI address, therefore we
can't just use <address/> blindly. But what we can do, is
introduce <address/> under the <target/> element. This is also
more conceptual, as knobs under <target/> control guest visible
config of memory device (and .memaddr surely falls into that
category).
NB, SgxEPCDeviceInfo struct in QMP definition also has .memaddr
attribute, but because of the way we build cmd line there's no
(easy) way to set the attribute. So ignore that for now.
