fileset: make debugfileset filter repository files

This prepares for the structural change of the fileset. A computed fileset
will no longer be a set of files, but a boolean function (i.e. matcher) to
test if an input file matches the given fileset expression.

--all-files option is added because some examples in the test need to scan
files across revisions.
