[Qemu-devel] [PATCH RFC 02/21] qapi: Generate up-to-date copyright notice

[Markus Armbruster <armbru@redhat.com>]

Each generator carries a copyright notice for the generator itself,
and another one for the files it generates.  Only the former have been
updated along the way, the latter have not, and are all out of date.

Fix by copying the generator's copyright notice to the generated files
instead.
