0c7674d027 rpc: eliminate static function virNetLibsshSessionAuthMethodsFree()
This function is only called from one place, and has, well... not a
*misleading* name, but it doesn't fit the standard frame of functions
that end in "Free" (it doesn't actually free the object pointed to by
its argument, but frees *some parts* of the content of the object).

Rather than try to think up an appropriate name, let's just move the
meat of this function into its one and only caller,
virNetLibsshSessionDispose(), which will allow us to convert its
VIR_FREEs into g_free in a future patch.

f772c48697 conf: simplify virDomainCapsDispose()
virDomainCapsDispose() was the only caller of
virDomainCapsStringValuesFree(), which 1) didn't actually free the
object it was called with, but only cleared it, making it less
mechanical to convert from VIR_FREE to g_free (since it's not
immediately obvious from looking at virDomainCapsStringValuesFree()
that the pointers being cleared will never again be used).

We could have renamed the function to virDomainCapsStringValuesClear()
to side-step the confusion of what the function actually does, but
that would just make the upcoming switch from VIR_FREE to g_free
require more thought. But since there is only a single caller to the
function, and it is a vir*Dispose() function (indicating that the
object containing the virDomainCapsStringValues is going to be freed
immediately after the function finishes), and thus VIR_FREE() *could*
be safely replaced by g_free()), we instead just move the contents of
virDomainCapsStringValuesFree() into virDomainCapsDispose() (and
*that* function will be trivially converted in an upcoming
"mechanical" patch).

1745297d51 rpc: rename virNetSessionAuthMethodsFree to virNetSessionAuthMethodsClear
This is another *Free() function that doesn't free the object it is
passed. Instead it frees and clears some parts of the object.

In this case, the function is actually called from two places, and one
of them (virNetSSHSessionAuthReset) appears to be assuming that the
pointers actually *will* be cleared. So the proper thing to do here
(?) is to rename the function to virNetSSHSesionAuthMethodsClear().

(NB: virNetSSHSessionAuthReset is seemingly never called from
anywhere. Is this one of those functions that actually *is* called by
some strange MACRO invocation? Or it is truly one of those
"written-but-never-used" functions that can be deleted? (if the latter
is the case, then I would rather move the contents of
virNetSessionAuthMethodsFree() into its only other caller,
virNetSSHSessionDispose(), so that the VIR_FREEs could be replaced
with g_free.)

5fb0c789c3 qemu: replace VIR_FREE with g_free in qemuFirmware*FreeContent()
These functions are all only called as a part of qemuFirmwareFree(),
which frees the qemuFirmware object before return, so we can be sure
none of the pointers is referenced after freeing (and thus there is no
need to clear any of them).

e7942f65c9 qemu: pass pointers instead of copying objects for qemuFirmware*FreeContent()
These functions all cooperate to free memory pointed to by a single
object that contains (doesn't *point to*, but actually contains)
several sub-objects. They were written to send copies of these
sub-objects to subordinate functions, rather than just sending
pointers to the sub-objects.

Let's change these functions to just send pointers to the objects
they're cleaning out rather than all the wasteful and pointless
copying.

e1b02e3a56 qemu: rename virFirmware*Free() functions to have more accurate names
Several functions had the names virFirmware[something]Free(), but they
aren't taking a pointer to some object and freeing it. Instead, they
are making a copy of the content of an entire object, then Freeing the
objects pointed to by that content.

As a first step in a too-complicated cleanup just to eliminate a few
occurrences of VIR_FREE(), this patch renames those functions to more
accurately reflect what they do - they Free the *Content* of their
arguments.

8626fb378c util: rename two *Free() functions while changing VIR_FREE to g_free
dhcpHostFree() and addnHostFree() don't follow the normal pattern of
*Free functions in the rest of libvirt code - they are actually more
similar to the *Dispose() functions, in that they free all subordinate
objects, but not the object pointed to by the argument
itself. However, the arguments aren't virObjects, so it wouldn't be
proper to name them *Dispose() either.

They *currently* behave similar to a *Clear() function, in that they
free all the subordinate objects and nullify the pointers of those
objects. HOWEVER, we don't actually need or want that behavior - the
two functions in question are only called as part of a higher level
*Free() function, and the pointers are not referenced in any way
between the time they are freed and when the parent object is freed.

So, since the current name isn't correct, nor is *Dispose(), and we
want to change the behavior in such a way that *Clear() also wouldn't
be correct, lets name the functions *FreeContent(), which is an
accurate description of what the functions do, and what we *want* them
to do.

And since it's such a small patch, we can go ahead and change that
behavior - replacing the VIR_FREEs with g_free.

currently is, move the macOS part to a separate branch.

What happens is that new virCgroup is created and stored into

into where another virCgroup is created and @parent is replaced
with this new virCgroup. But nothing freed the old @parent.

993351ff62 build: fix specfile logic for disabling netcf
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.
