Makes sense to me.

This would be better as enum qemud_save_formats rather than int.  No
need for a forward declaration, since you implemented the function in
topological order.

Likewise.

ACK with those nits fixed.  So I squashed in 5/5 to keep 'make
syntax-check' happy for the purposes of 'git bisect', made the above
changes, and pushed this patch.  The rest of your series still needs a v4.
