libqtest: Document calling conventions
We have two flavors of vararg usage in qtest: qtest_hmp() etc. work
like sprintf(), and qtest_qmp() etc. work like qobject_from_jsonf().
Spell that out in the comments.
Also add GCC_FMT_ATTR() to qtest_hmp() etc. so that the compiler can
flag incorrect use.
We have some cleanup work to do before we can do the same for
qtest_qmp() etc. This would get us the same better-than-nothing
checking we already have for qobject_from_jsonf(): common incorrect
uses of supported conversion specifications will be flagged
(e.g. passing a double for %d), but use of unsupported ones won't.
