Comment:

 Implement caching

 This is conservative in how it caches database dictionaries, but more
 aggressive with process objects.

 * bug1953:
   cache Change instances
   cache BuildRequest instances
   cache SourceStamps; add a fakemaster module to help tests
   cache db results
   Add @base.cached for DBConnectorComponents
   add master.caches, so-far unused
   AsyncLRUCache changes

 Fixes #1953.
