The FS_Info module has a pseudo multi-object interface and used the
constructor to load the cache.  However all the data in the class is
static.  An FS_Info object doesn't contain any member variables, yet was
needed just to call the member functions.

Make all the member functions static removing the need to use any
FS_Info objects and provide an explicit load_cache() method.
