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
Alternatively, rewrite to virXMLPropTristateXXX() could have gone in the
first, followed by change of struct members to virTristateXXX which
would have produced smalled diff. But I guess it doesn't matter.
