The old minimum values are rather large, making it time consuming to test related behaviour. Additionally the current limits, especially for multixacts, can be problematic in space-constrained systems. 10000000 multixacts can contain a lot of members. Since there's no good reason for the current limits, lower them a good bit. Setting them to 0 would be a bad idea, triggering endless vacuums, so still retain a limit. While at it fix autovacuum_multixact_freeze_max_age to refer to multixact.c instead of varsup.c.
