small paths code rearrangement (#4007)
small cleanup in paths, primarily splitting files
so that file contents are more clearly owned, which should be a little better for readability and code placement.

Also renames `ServicePrefix` to `BuildPrefix` in
anticipation of multi-service prefixes.

no logic changes, just movement/renaming.
