a152d856c3 virDomainNumatuneNodeSpecified: Fix const correctness
The virDomainNumatuneNodeSpecified() function does not write into
passed @numatune pointer, it just reads from it. Therefore, the
argument should be const, which allows this function to be called
from places where virDomainNuma is already const (e.g. domain
validation code).

af621caa6b conf: numa: Allow formatting 'none' values for 'associativity' and 'policy' of cache
The parser makes the values mandatory and also the qemu code implements
actions for those values. The formatter skips them though. Since
format+parse is used to copy the XML at startup a definition with those
values can't be started.

a0065f9728 conf: Don't format firmware type/features when migrating
The combination of explicit firmware paths, which we now
produce in all cases, and firmware autoselection knobs is
explicitly rejected by libvirt 8.6.0 and newer.

Right now we produce inherently migratable XML in all cases,
since we always strip those bits, but that's going to change
soon. To prepare for that, make sure that we always skip the
problematic elements and attributes when preparing a
migratable XML.

The destination will simply receive a fully specified firmware
configuration, which is indistinguishable from one that was
manually provided by the user and is thus accepted by any old
version of libvirt, regardless of whether or not firmware
autoselection was used on the source host.

ccf4aa37a0 conf: Remove some firmware validation checks
libvirt 8.6.0 introduced these checks and very clearly delineated
two possible firmware selection scenarios: manual firmware
selection, where the user is responsible for providing all
information, and firmware autoselection, where a list of desired
features is provided and everything else is handled by libvirt.

In the interest of maintaining the clear separation between these
two scenarios, setting most attributes when firmware autoselection
is active will result in the configuration being rejected.

This works fine, but is unnecessarily restrictive: in most cases,
the additional information that the user has provided matches
the information that libvirt would have discovered on its own by
looking at firmware descriptors, and asking the user to scrub it
from the XML only result in pointless friction.

Remove these checks entirely.

Unsurprisingly, this results in a few test cases that were
rejected until now to suddenly start working and producing
sensible results.

The firmware-auto-efi-loader-path-nonstandard test case is
notable: while we can now enable the xml2xml part of the test,
the xml2argv part is still failing, although in a slightly
different way. This is expected: since the firmware binary is a
non-standard one, libvirt is unable to figure out the missing
information from a firmware descriptor, and the configuration
is still ultimately an invalid one. However, if we were to find
such a configuration on disk at daemon startup, we would not
ignore it completely and instead would offer the user a chance
to fix it.

b1b037fa5b Introduce VIR_DOMAIN_PAUSED_API_ERROR
Some APIs (migration, save/restore, snapshot, ...) require a domain to
be suspended temporarily. In case resuming the domain fails, the domain
will be unexpectedly left paused when the API finishes. This situation
is reported via VIR_DOMAIN_EVENT_SUSPENDED event with
VIR_DOMAIN_EVENT_SUSPENDED_API_ERROR detail. But we do not have a
corresponding reason for VIR_DOMAIN_PAUSED state and the reason would
remain set to the value used when the domain was paused. So the state
reason would suggest the operation is still running.

This patch changes the state reason to a new VIR_DOMAIN_PAUSED_API_ERROR
to make it clear the API that paused the domain already finished, but
failed to resume the domain.

172dd3d9f7 conf: Make macvtap ethernet share host view
When fetching stats for a domain's <interface/>, or when setting
up its QoS, we can face two situations:

1) the device "shares" the host view, meaning each packet
   sent/received on the interface by a domain is accounted for in
   the same category on the host, or

2) the device is at the other side, and a packet send by a
   domain, is in fact packet received on the host.

This fact affects whether we need to swap RX/TX values when
fetching stats, or setting up QoS. We have this convenient helper
function (virDomainNetTypeSharesHostView()), which returns to
which category given interface type falls into.

Now, for unmanaged type='ethernet' our options are quite limited,
because it's user's responsibility to set up the host side of the
interface. And it can be just anything. Fortunately, we have
another convenience function (virNetDevMacVLanIsMacvtap()), which
determines whether given interface is a macvtap (which is
notoriously known for falling into the first category).
Let's use it to help virDomainNetTypeSharesHostView() determine
the view more accurately.

b3b81e60e4 conf: Change handling for empty NVRAM path
Right now, this results in loader->nvram being NULL, which is
reasonable: loader->nvramTemplate is stored separately, so if
the <nvram> element doesn't contain a path there is really no
useful information inside it.

However, this is about to change, so we will find ourselves
needing to hold on to loader->nvram even when no path is
present. Change the firmware handling code so that such a
scenario is dealt with appropriately.
