[Qemu-devel] [PATCH v2 for-2.9 15/47] qapi: Conjure up QAPIDoc.ArgSection for undocumented members

[Markus Armbruster <armbru@redhat.com>]

qapi2texi.py already conjures up ArgSections for undocumented
enumeration values, in texi_enum.  Drop that, and conjure them up for
all kinds of "arguments" (enumeration values, object and alternate
type members) in qapi.py instead.

Take care to keep generated documentation exactly the same for now.
