Replace combinations of xalloc_oversized and VIR_ALLOC_N_QUIET by using
g_malloc0_n which does the checking internally.

This conversion is done with a semantic difference and slightly higher
memory requirements as I've opted to allocate one chunk more than
necessary rather than trying to accomodate the NUL byte separately.

After conversion to g_strdup, the helpers now always return success.
Remove the return value to simplify the callers.

Note that many occurrences of these is in the code generated by
gendispatch.pl. Since gendispatch aggregates many cases together an
incremental conversion would require more invasive changes to
gendispatch for the time of conversion which doesn't make sense.

Also in many cases the helper was the last place where the 'error:'
label was used and thus also those conversions must be included in this
patch.

In few places we have the following code pattern:

  int ret;
  ... /* @ret is not accessed here */
  ret = f(...);
  return ret;

This pattern can be written less verbose:

  ...
  return f(...);

This patch was generated with following coccinelle spatch:

  @@
  type T;
  constant C;
  expression f;
  identifier ret;
  @@
  -T ret = C;
   ... when != ret
  -ret = f;
  -return ret;
  +return f;

Afterwards I needed to fix a few places, e.g. comment in
virDomainNetIPParseXML() was removed too because coccinelle
thinks it refers to @ret while in fact it doesn't. Also in few
places it replaced @ret declaration with a few spaces instead of
removing the line. But nothing terribly wrong.

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].

In domain_conf.c we have virDomainSCSIDriveAddressIsUsed()
function which returns true or false if given drive address is
already in use for given domain config or not. However, it also
takes a shortcut and returns true (meaning address in use) if the
unit number equals 7. This is because for some controllers this
is reserved address. The limitation comes mostly from vmware and
applies to lsilogic, buslogic, spapr-vscsi and vmpvscsi models.
On the other hand, we were not checking for the maximum unit
