largefiles: rename functions and methods to match desired behavior

The original intent was that the largefiles would primarily be in the
repository, with the global cache being only that--a cache.  The naming
conventions and actual intent have both strayed.  In this first patch, the
naming conventions are switched to match the actual intent, as are the
configuration options.
