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).

Mercurial supports several ways to specify individual revisions. A plain integer is treated as a revision number. Negative integers are treated as sequential offsets from the tip, with -1 denoting the tip, -2 denoting the revision prior to the tip, and so forth. A 40-digit hexadecimal string is treated as a unique revision identifier. A hexadecimal string less than 40 characters long is treated as a unique revision identifier and is referred to as a short-form identifier. A short-form identifier is only valid if it is the prefix of exactly one full-length identifier. Any other string is treated as a bookmark, tag, or branch name. A bookmark is a movable pointer to a revision. A tag is a permanent name associated with a revision. A branch name denotes the tipmost revision of that branch. Bookmark, tag, and branch names must not contain the ":" character. The reserved name "tip" always identifies the most recent revision. The reserved name "null" indicates the null revision. This is the revision of an empty repository, and the parent of revision 0. The reserved name "." indicates the working directory parent. If no working directory is checked out, it is equivalent to null. If an uncommitted merge is in progress, "." is the revision of the first parent.
