We should not mock stat64() when building on Apple Silicon,
because the declaration is not present in the header file.
Detect this situation and handle it gracefully.

On macOS, most of the symbols and declarations that we look at
to determine which versions of stat() we need to mock are not
present; on the other hand, there are some specific wrinkles
that are introduced with Apple Silicon which we will need to
take care of.
To avoid making the logic even more of an opaque mess than it
currently is, move the macOS part to a separate branch.
This commit is better viewed with 'git show -w'.

Commit <318d807a0bd3372b634d1952b559c5c627ccfa5b> added a fix to skip
most of the block stat code to not log error message for missing storage
sources but forgot to increase the recordnr counter.

What happens is that new virCgroup is created and stored into
@parent. Then, if @tokens is not empty the for() loop is entered
into where another virCgroup is created and @parent is replaced
with this new virCgroup. But nothing freed the old @parent.

I *thought* I had tested all the combinations of manually setting
--without netcf, different versions of Fedora, etc, but apparently
not.
The check in libvirt.spec.in to see if the target was an older Fedora
or older RHEL would alway resolve to true, because, e.g., if {?fedora}
is undefined, then "0%{?fedora} < 34" is "0 < 34", which is always
true. Since both {?fedora} and {?rhel} are never defined at the same
time, the result of the entire expression is always true.
Fix this by qualifying each subexpression.

The use case VIR_ALLOC_VAR deals with is very unlikely. We had just 2
legitimate uses, which were reimplemented locally using g_malloc0 and
sizeof instead as they used a static number of members of the trailing
array.
Remove VIR_ALLOC_VAR since in most cases the direct implementation is
shorter and clearer and there are no users of it currently.

In this case we need a 'struct ethtool_gfeatures' followed by two
