Create a new erfs.c file that will be used to hold all the refs code that is backend agnostic and will be shared across all backends.

The reason we renamed everything to refs-be-files.c in the previous patch and now start moving the common code back to the new refs.c file instead of the other way around is the etive volumes of code.

With the ref_cache, packed refs and loose ref handling that are all part of the files based implementation the backend specific part of the old refs.c file is several times larger than the backend agnostic part. Therefore it makes more sense to first rename everything to be part of the files based backend and then move the parts that can be used as common code back to refs.c.
