ca04290be3 test: snapshot revert: always error out if VM XML is missing
We should have this check even if FORCE flag is used because later we
unconditionally copy the `snap->def->dom` and error out if there is no
copy created. The test driver will always save the VM XML when creating
new snapshot.

There are a lot of places where we call virInterfaceDefFree()

This also fixes a memory leak in udevInterfaceGetXMLDesc() which

857df2fe50 lib: Drop intermediary return variables
In a few places we declare a variable (which is optionally
followed by a code not touching it) then set the variable to a
value and return the variable immediately. It's obvious that the
variable is needless and the value can be returned directly
instead.

This patch was generated using this semantic patch:

  @@
  type T;
  identifier ret;
  expression E;
  @@
  - T ret;
  ... when != ret
      when strict
  - ret = E;
  - return ret;
  + return E;

After that I fixed couple of formatting issues because coccinelle
formatted some lines differently than our coding style.

5c359377a0 capabilities: Expose NUMA memory side cache
Memory on a NUMA node can have a side caches. Configuring these
for a domain was implemented in v6.6.0-rc1~249 and friends.
However, up until now mgmt applications did not really know what
values to pass because we were not exposing caches of the host.
With recent enough kernel these are exposed under sysfs and with
a bit of parsing we can extend our capabilities XML. The sysfs
structure is documented in kernel's
Documentation/admin-guide/mm/numaperf.rst and basically maps in
1:1 fashion to our virNumaCache structure.

What this function really does it takes ownership of all pointers
passed (well, except for the first one - caps - to which it
registers new NUMA node). But since all info is passed as a
single pointer it's hard to tell (and use g_auto*). Let's use
double pointers to make the ownership transfer obvious.

c8238579fb lib: Drop internal virXXXPtr typedefs
Historically, we declared pointer type to our types:

  typedef struct _virXXX virXXX;
  typedef virXXX *virXXXPtr;

But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.

This change was generated by a very ugly shell script that
generated sed script which was then called over each file in the
repository. For the shell script refer to the cover letter:

b0f78d626a lib: Fix calling of virNetworkUpdate() driver callback
The order in which virNetworkUpdate() accepts @section and
@command arguments is not the same as in which it passes them
onto networkUpdate() callback. Until recently, it did not really
matter, because calling the API on client side meant arguments
were encoded in reversed order (compared to the public API), but
then on the server it was fixed again - because the server
decoded RPC (still swapped), called public API (still swapped)
and in turn called the network driver callback (with reversing
the order - so magically fixing the order).

Long story short, if the public API is called even number of
times those swaps cancel each other out. The problem is when the
API is called an odd numbed of times - which happens with split
daemons and the right URI. There's one call in the client (e.g.
virsh net-update), the other in a hypervisor daemon (say
virtqemud) which ends up calling the API in the virnetworkd.

The fix is obvious - fix the order in which arguments are passed
to the callback.

But, to maintain compatibility with older, yet unfixed, daemons
new connection feature is introduced. The feature is detected
just before calling the callback and allows client to pass
arguments in correct order (talking to fixed daemon) or in
reversed order (talking to older daemon).

Unfortunately, older client talking to newer daemon can't be
fixed. Let's hope that it's less frequent scenario.
