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
(networkxml2firewalltest, nwfilterebiptablestest,
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.

At this moment it is not possible to launch a 'riscv64' domain if a CPU
definition is presented in the domain. For example, adding this CPU
definition:
<cpu mode='custom' match='exact' check='none'>
<model fallback='forbid'>rv64</model>
</cpu>
Will trigger the following error:
$ sudo ./run tools/virsh start riscv-virt1
error: Failed to start domain 'riscv-virt1'
error: this function is not supported by the connection driver:
cannot update guest CPU for riscv64 architecture
The error comes from virCPUUpdate(), via qemuProcessUpdateGuestCPU(),
and it's caused by the absence of the 'update' API in the existing
RISC-V driver.
Add an 'update' API impl to the RISC-V driver to allow for CPU
definitions to be declared in RISC-V domains. This API was copied from
the ARM driver (virCPUarmUpdate()) since it's a good enough
implementation to get us going.

- querying is handled via the bulk stats API which is flexible:
- we use virTypedParamListAddUnsigned to use the bigger type only if
necessary
- most users don't even notice because the bindings abstract the
data types
Apart from the code modifications we also improve the documentation
