Currently, firmware selection is performed as part of the
domain startup process. This mostly works fine, but there's a
significant downside to this approach: since the process is
affected by factors outside of libvirt's control, specifically
the contents of the various JSON firmware descriptors and
their names, it's pretty much impossible to guarantee that the
outcome is always going to be the same. It would only take an
edk2 update, or a change made by the local admin, to render a
domain unbootable or downgrade its boot security.
To avoid this, move firmware selection to the postparse phase.
This way it will only be performed once, when the domain is
first defined; subsequent boots will not need to go through
the process again, as all the paths that were picked during
firmware selection are recorded in the domain XML.
Care is taken to ensure that existing domains are handled
correctly, even if their firmware configuration can't be
successfully resolved. Failure to complete the firmware
selection process is only considered fatal when defining a
new domain; in all other cases the error will be reported
during startup, as is already the case today.

QEMU's "reconnect" option of "-netdev stream" tells QEMU to
periodically (period is given in seconds as an argument to the option)
attempt to reconnect to the same passt socket to which it had
originally connected to. This is useful in cases where the passt
process terminates, and libvirtd starts a new passt process in its
place (which doesn't happen yet, but will happen automatically after
an upcoming patch in this series).
Since there is no real hueristic for determining the "best" value of
the reconnect interval, rather than clutter up config with a knob that
nobody knows how to properly twiddle, we just set the reconnect timer
to 5 seconds.
"-netdev stream" first appeared in QEMU 7.2.0, but the reconnect
option won't be available until QEMU 8.0.0, so we need to check QEMU

'domaincapstest' is currently skipping RISC-V tests. Let's enable it.
The decision of enabling the "virt" machine is based on the idea that
this is the most used QEMU RISC-V machine in the community and it's the
most likely to be widely supported in the long run.

net-user-passt.args was generated early during testing of the passt
qemu commandline, when qemuxml2argvtest was using
DO_TEST("net-user-passt"). This was later changed to
DO_TEST_CAPS_LATEST(), so the file net-user-passt.x86_64-latest.args
is used instead, but the original (now unused) test file was
accidentally added to the original patch. This patch removes it.

This attribute was added to support setting the --interface option for
passt, but in a post-push/pre-9.0-release review, danpb pointed out
that it would be better to use the existing <source dev='xxx'/>
attribute to set --interface rather than creating a new attribute (in
the wrong place). So we remove backend/upstream, and change the passt
commandline creation to grab the name for --interface from source/dev.

Currently, the ThreadContext object is generated whenever we see
.host-nodes attribute for a memory-backend-* object. The idea was
that when the backend is pinned to a specific set of host NUMA
nodes, then the allocation could be happening on CPUs from those
nodes too. But this may not be always possible.
Users might configure their guests in such way that vCPUs and
corresponding guest NUMA nodes are on different host NUMA nodes
than emulator thread. In this case, ThreadContext won't work,
because ThreadContext objects live in context of the emulator
thread (vCPU threads are moved around by us later, when emulator
thread finished its setup and spawned vCPU threads - see
qemuProcessSetupVcpus()). Therefore, memory allocation is done by
emulator thread which is pinned to a subset of host NUMA nodes,
but tries to create a ThreadContext object with a disjoint subset
of host NUMA nodes, which fails.

This consists of (1) adding the necessary args to the qemu commandline
netdev option, and (2) starting a passt process prior to starting
qemu, and making sure that it is terminated when it's no longer
needed. Under normal circumstances, passt will terminate itself as
soon as qemu closes its socket, but in case of some error where qemu
is never started, or fails to startup completely, we need to terminate
passt manually.

This implements XML config to represent a subset of the features
supported by 'passt' (https://passt.top), which is an alternative
backend for emulated network devices that requires no elevated
privileges (similar to slirp, but "better").
Along with setting the backend to use passt (via <backend
type='passt'/> when the interface type='user'), we also support
passt's --log-file and --interface options (via the <backend>
subelement logFile and upstream attributes) and its --tcp-ports and
--udp-ports options (which selectively forward incoming connections to
the host on to the guest) via the new <portForward> subelement of
<interface>. Here is an example of the config for a network interface
that uses passt to connect:
<interface type='user'>
<mac address='52:54:00:a8:33:fc'/>
<ip address='192.168.221.122' family='ipv4'/>
<model type='virtio'/>
<backend type='passt' logFile='/tmp/xyzzy.log' upstream='eth0'/>
<portForward address='10.0.0.1' proto='tcp' dev='eth0'>
<range start='2022' to='22'/>
<range start='5000' end='5099' to='1000'/>
<range start='5010' end='5029' exclude='yes'/>
</portForward>
<portForward proto='udp'>
<range start='10101'/>
</portForward>
</interface>
In this case:
* the guest will be offered address 192.168.221.122 for its interface
via DHCP
* the passt process will write all log messages to /tmp/xyzzy.log
* routes to the outside for the guest will be derived from the
addresses and routes associated with the host interface "eth0".
* incoming tcp port 2022 to the host will be forwarded to port 22
on the guest.
* incoming tcp ports 5000-5099 (with the exception of ports 5010-5029)
to the host will be forwarded to port 1000-1099 on the guest.
* incoming udp packets on port 10101 will be forwarded (unchanged) to
the guest.
