I won't mix move and changes beside small ones like renaming following
the reasoning about move. But another patch could go.
About rebasing and complexity I think is a balance between effort and gain.
We are improving code so I would spend a bit more if result is much better.
About gboolean I would say that C99 have also a stdbool.h (and actually some
code in spice-server is using it).
Can you suggest something to add to the commit message?
I agree to the ack too.
