This series replaces some recurring boilerplate code in src/conf/ regarding
the extraction of a virTristate(Switch|Bool) XML attribute.
The boilerplate code looks roughly like this,
g_autofree char *str = NULL;
if (str = virXMLPropString(node, ...)) {
int val;
if ((val = virTristateBoolTypeFromString(str)) <= 0) {
virReportError(...)
return -1;
}
def->... = val;
}
with some variations regarding how `str` is free'd in case of later re-use,
the exact error message for invalid values, whether or not
`VIR_TRISTATE_(SWITCH|BOOL)_ABSENT` is explicitly checked for (`val < 0` vs.
`val <= 0`), whether an intermediate variable is used or the value is assigned
directly, and in some cases the conditions in the two if-blocks are merged.
As a side effect, this makes the error messages for invalid values in these
attributes much more consistent and catches some instances where e.g.
`<foo bar="default"/>` would incorrectly be accepted.

V2: https://listman.redhat.com/archives/libvir-list/2021-March/msg00994.html
Changes since V2:
* Fixed the -Wtautological-unsigned-enum-zero-compare issues in the first
part of the series. These issues were solved later in the series, but
this change makes it easier to bisect in the future.
I was thinking about only re-sending the first couple of patches, but the
latter part would have endet up with quite a few conflicts, so I am sending
it in its entirety, again. Sorry for the spam!
Cheers,
Tim
