agent: Make the request origin a part of the cache items.

Browse source 
* agent/cache.c (agent_put_cache): Add arg 'ctrl' and change all
callers to pass it.
(agent_get_cache): Ditto.

* agent/cache.c (struct cache_items_s): Add field 'restricted'.
(housekeeping): Adjust debug output.
(agent_flush_cache): Ditto.
(agent_put_cache): Ditto.  Take RESTRICTED into account.
(agent_get_cache): Ditto.

If requests are coming from different sources they should not share the
same cache.  This way we make sure that a Pinentry pops up for a
remote request to a key we have already used locally.
