Comment(by andrea):

 I added a replaycache_add_test_and_elapsed() function for the replay cache
 which provides the elapsed time since the last time the digest in question
 was seen when there's a hit, to facilitate the log messages in that case
 in rend_service_introduce().

 I've also added a counter for INTRODUCE2 cells seen, since the old
 implementation of intro_point_accepted_intro_count() relied on the size of
 the accepted_intro_rsa_parts digest map for that, which will not work
 reliably now that accepted_intro_rsa_parts is a replaycache_t and ages out
 old values.
