Bug 695892: Fix incremental updates of documents with xref streams.

Simon Reinhardt points out that writexrefstream calls pdf_update_stream
on an object, rather than on a reference. The code as written fails to
do the update, and the updated file is broken.

I fix this here by updating pdf_update_stream to be able to work
with both objects and references. This is in contrast to his patch
which would create a reference for the sole purpose of performing
the update.
