alloc: factor out commit index 

We keep a static counter to set the commit index on newly
allocated objects. However, since we also need to set the
index on any_objects which are converted to commits, let's
make the counter available as a public function.

While we're moving it, let's make sure the counter is
allocated as an unsigned integer to match the index field in
"struct commit".
