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

The code pretends that it cares about clearing the secret values, but
passes the secret value to a realloc, which may copy the value somewhere
else and doesn't sanitize the original location when it does so.
Since we want to construct a string from the value, let's copy it to a
new piece of memory which has the space for the 'NUL' byte ourselves, to
prevent a random realloc keeping the data around.
While at it, use virSecureErase instead of VIR_DISPOSE_N since it's
being phased out.

Use a single buffer for the secret to make it easier to follow it's
