Subject: [PATCH] ui: rename cursor_{get->ref}, return it
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

The naming is more conventional in QEMU code, and allows to simplify
some code by changing the API design, so it returns the input parameter,
instead of void.
