Add a :namespace: option to the qapi-doc directive, which inserts a
qapi:namespace directive into the start of the generated document. This,
in turn, associates all auto-generated definitions by this directive
with the specified namespace.

The source info for these generated lines are credited to the start of
the qapi-doc directive, which isn't precisely correct, but I wasn't sure
how to get it more accurate without some re-parsing shenanigans.
