The function is now unused and motivated users to write crazy parsers
which were hard to understand, had pointless error paths just to avoid
few memory allocations.
Remove the function as we're fine with g_strndup and virStrcpy.

15 out of 72 invocations of virStrcpy(Static) ignore the return value as
it's either impossible to fail or in certain cases a truncated copy is
still good enough. Unfortunately virStrcpy doesn't copy anything in
such case as the checks are done first.
Fix this by using g_strlcpy for the implementation and removing
G_GNUC_WARN_UNUSED_RESULT from the function so that callers can decide
when it's okay.

virStringListAdd hides the fact that a O(n) count of elements is
performed every time it's called which makes it inefficient.
Stop supporting such semantics and remove the helpers. Users have a
choice of using GSList or an array with a counter variable rather than
repeated lookups.

Currently, we are mixing: #if HAVE_BLAH with #if WITH_BLAH.
Things got way better with Pavel's work on meson, but apparently,
mixing these two lead to confusing and easy to miss bugs (see
31fb929eca for instance). While we were forced to use HAVE_
prefix with autotools, we are free to chose our own prefix with
meson and since WITH_ prefix appears to be more popular let's use
it everywhere.

In a few places our code relies on the fact that virAsprintf()
not only prints to allocated string but also that it returns the
length of that string. Fortunately, only few such places were
identified:
https://www.redhat.com/archives/libvir-list/2019-September/msg01382.html
In case of virNWFilterSnoopLeaseFileWrite() and virFilePrintf()
we can use strlen() right after virAsprintf() to calculate the
length. In case of virDoubleToStr() it's only caller checks for
error case only, so we can limit the set of returned values to
just [-1, 0].
