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.

During hotplug of a NVMe disk we need to adjust the memlock
limit. The computation of the limit is handled by
qemuDomainGetMemLockLimitBytes() which looks at given domain
definition and accounts for various device types (as different
types require different amounts). But during disk hotplug the
disk is not added to domain definition until the very last
moment. Therefore, qemuDomainGetMemLockLimitBytes() has this
@forceVFIO argument which tells it to assume VFIO even if there
are no signs of VFIO in domain definition. And this kind of
works, until the amount needed for NVMe disks changed (in
v9.3.0-rc1~52). What's missing in the commit is making @forceVFIO
behave the same as if there was an NVMe disk present in the
domain definition.
But, we can do even better - just mimic whatever we're doing for
hostdevs. IOW - introduce qemuDomainAdjustMaxMemLockNVMe() that
behaves the same as qemuDomainAdjustMaxMemLockHostdev().
There are subtle differences though:
1) qemuDomainAdjustMaxMemLockHostdev() can afford placing hostdev
right at the end of vm->def->hostdevs, because the array was
already reallocated (at the beginning of
qemuDomainAttachHostPCIDevice()). But
qemuDomainAdjustMaxMemLockNVMe() doesn't have that luxury.
2) qemuDomainAdjustMaxMemLockHostdev() places a
virDomainHostdevDef pointer into domain definition, while
qemuDomainStorageSourceAccessModifyNVMe() (which calls
qemuDomainAdjustMaxMemLock()) sees a virStorageSource pointer
but domain definition contains virDomainDiskDef. But that's
okay, we can create a dummy disk definition and append it into
the domain definition.
After this, qemuDomainAdjustMaxMemLock() can be called with
@forceVFIO = false, as the disk is now part of domain definition
(when computing the new limit).

With musl-1.2.3: I get the following macros defined (from
$builddir/meson-config.h):
#define WITH_LSTAT 1
#define WITH_LSTAT64 1
#define WITH_LSTAT_DECL 1
#define WITH_STAT 1
#define WITH_STAT64 1
#define WITH_STAT_DECL 1
#define WITH___LXSTAT 1
#define WITH___LXSTAT64 1
#define WITH___XSTAT 1
#define WITH___XSTAT64 1
which in turn means the virmockstathelpers.c ends up defining:
MOCK_STAT64
MOCK_LSTAT64
But with musl-1.2.4 everything changes and the set of defined
macros gets simplified to:
#define WITH_LSTAT 1
#define WITH_LSTAT_DECL 1
#define WITH_STAT 1
#define WITH_STAT_DECL 1
#define WITH___LXSTAT 1
#define WITH___XSTAT 1
which results in no MOCK_* macros defined in
virmockstathelpers.c, i.e. no stat() mocking, nada. The reason
for this simplification are these musl commits [1][2] which
removed all 64 bit aliases. And that's not what our logic for
deciding what flavor of stat() to mock counted with.
Nevertheless, we do build with Alpine Linux in our CI, so how
come we don't see this problem there? Well, simply because Alpine
Linux maintainers decided to revert the commits [3][4]. But on
distributions that use vanilla musl, this problem can be seen
easily.

Neither of tests that use virfirewallmock.c

nwfilterxml2firewalltest, virfirewalltest) really call
virFindFileInPath(). But at least networkxml2firewalltest calls
virFirewallDIsRegistered(), under the hood. Now, the actual
implementation connects to dbus and something, which is
definitely not what we want in our test suite.
Therefore, drop virFindFileInPath() implementation and provide
implementation for virFirewallDIsRegistered() which just returns
-2 to signal that firewalld is not registered.
