Add "Returns:" field list syntax to QAPI Commands.
Like "Arguments:" and "Errors:", the type name isn't currently processed
for cross-referencing, but this will be addressed in a forthcoming
commit.
This patch adds "errors" as a GroupedField, which means that multiple
return values can be annotated - this is only done because Sphinx does
not seemingly (Maybe I missed it?) support mandatory type arguments to
Ungrouped fields. Because we want to cross-reference this type
information later, we want to make the type argument mandatory. As a
result, you can technically add multiple :return: fields, though I'm not
aware of any circumstance in which you'd need or want
to. Recommendation: "Don't do that, then."
Since this field describes an action/event instead of describing a list
of nouns (arguments, features, errors), I added both the imperative and
indicative forms (:return: and :returns:) to allow doc writers to use
whichever mood "feels right" in the source document. The rendered output
will always use the "Returns:" label, however.
I'm sure you'll let me know how you feel about that. O:-)
