2019-04-16store: Memoize 'built-in-builders' call directly in <store-connection>....The caching strategy introduced in 40cc850aebb497faed0a11d867d8fcee729023df was ineffective since we regularly start from an empty object cache.

Use it as second argument of 'for-each' in base case. Ludovic Courtès
2017-07-02store: 'references/substitutes' save an RPC is the trivial case....* guix/store.scm (references/substitutes): Save a 'substitutable-path-info' call when MISSING is empty. Ludovic Courtès
2017-06-22store: Define a default port for TCP connections....* guix/store.scm (%default-guix-port): New variable. (connect-to-daemon)[connect]: Use it when (uri-port uri) is #f. * doc/guix.texi (The Store): Mention the default port number. Ludovic Courtès
