[Qemu-devel] [PATCH v12 09/36] qapi: Factor out QAPISchemaObjectTypeMember.check_clash()

[Eric Blake <eblake@redhat.com>]

From: Markus Armbruster <armbru@redhat.com>

While there, stick in a TODO change key of seen from QAPI name to C
name.  Can't do it right away, because it would fail the assertion for
tests/qapi-schema/args-has-clash.json.
