store: move top file walk to a separate function

Some extensions find it useful to be able to walk the non-data files in the
repo, so I'm moving that part of the walk to a separate function.

In particular, this allows an extension to interact with only the non-filelog
store data (for instance, when cloning everything but filelogs).
