o Hidden Service Enhancement
Client now uses an introduction point failure cache to know when to
fetch or keep a descriptor in their cache.
When fetching a descriptor, for every introduction points in it, we look
them up in the failure cache to know if we keep the descriptor or not.
For this to work, everytime an introduction points is discarded (ex:
receiving a NACK), we note it down in our introduction cache. If all
introduction points for an onion service are in our failure cache, we
discard the descriptor and fetch a new one.
See rendcache.c for a detailed explanation of the cache's behavior.
