It's almost like we've anticipated this. Our XML parser and
formatter handles @address and @dev attributes of <portForward/>
element completely independent of each other. And as of commit
2023_03_29.b10b983~3 passt allows handling these two separately
too. All that's left is generate the cmd line according to this
new fact.

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.

After a QEMU domain is started, among other thing we query memory
device information. And while memory address is returned by QEMU
for all models, we store it only for DIMMs and NVDIMMs. Do store
it for VIRTIO_MEM and VIRTIO_PMEM too.
This effectively reports the address the virtio-mem/virtio-pmem
is mapped to in live XML.

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.

We have plenty of generic typedefs (that basically just alias a
struct, or our popular virXXXPtr). Because we do not generate
HTML docs for it, the documentation is placed at random places,
e.g.: comment from virDomainPtr typedef ("a virDomainPtr is
pointer to a virDomain private structure ...") ends up after
virDomainProcessSignal enum block.
There are some less weird occurrences of this problem (e.g.
virBlkioParameterPtr), but yet - the typedef appears in TOC.
Therefore, generate a block for each typedef and put its
description there.

Again, this fixes the same problem as one of previous commits,
but this time for memory hotplug. Long story short, if there's a
domain running and the emulator thread is restricted to a subset
of host NUMA nodes, but the memory that's about to be hotplugged
requires memory from a host NUMA node that's not in the set we
need to allow emulator thread to access the node, temporarily.

Consider a domain with two guest NUMA nodes and the following
<numatune/> setting :
<numatune>
<memory mode="strict" nodeset="0"/>
<memnode cellid="0" mode="strict" nodeset="1"/>
</numatune>
What this means is the emulator thread is pinned onto host NUMA
node #0 (by setting corresponding cpuset.mems to "0"), and two
memory-backend-* objects are created:
-object '{"qom-type":"memory-backend-ram","id":"ram-node0", .., "host-nodes":[1],"policy":"bind"}' \
-numa node,nodeid=0,cpus=0-1,memdev=ram-node0 \
-object '{"qom-type":"memory-backend-ram","id":"ram-node1", .., "host-nodes":[0],"policy":"bind"}' \
-numa node,nodeid=1,cpus=2-3,memdev=ram-node1 \
Note, the emulator thread is pinned well before QEMU is even
exec()-ed.
Now, the way memory allocation works in QEMU is: the emulator
thread calls mmap() followed by mbind() (which is sane, that's
how everybody should do it). BUT, because the thread is already
restricted by CGroups to just NUMA node #0, calling:
mbind(host-nodes:[1]); /* made up syntax (TM) */
fails. This is expected though. Kernel was instructed to place
the memory at NUMA node "0" and yet, process is trying to place
it elsewhere.
We used to solve this by not restricting emulator thread at all
initially, and only after it's done initializing (i.e. we got the
QMP greeting) we placed it onto desired nodes. But this had its
own problems (e.g. QEMU might have locked pieces of its memory
which were then unable to migrate onto different NUMA nodes).
Therefore, in v5.1.0-rc1~282 we've changed this and set cgroups
upfront (even before exec()-ing QEMU). And this used to work, but
something has changed (I can't really put my finger on it).
Therefore, for the initialization start the thread with union of
all configured host NUMA nodes ("0-1" in our example) and fix the
placement only after QEMU is started.
NB, the memory hotplug suffers the same problem, but that will
be fixed in the next commit.
