  reflog: move the reflog implementation into refdb_fs References and their logs are logically coupled, let's make it so in the code by moving the fs-based reflog implementation to live next to the fs-based refs one. As part of the change, make the function take names rather than references, as only the names are relevant when looking up and handling reflogs.
