[ratelimits] new patches

[Vernon Schryver]

New patches and new versions of the existing RRL patches can be
found through the link labeled "Patch files for BIND9" on
http://www.redbarn.org/dns/ratelimits

The new patches are for the recent BIND 9.9.3 and BIND 9.8.5 releases.

The new versions of the existing patches:

  - address the issue raised by Bob Harold. RRL on recursive servers
     applies rate limits after waiting for recursion except on
     sub-domains of domains for which the server is authoritative.

  - fix the bug reported by Roy Arends in which "slipped" NXDOMAIN
     responses had rcode values of 0 (NoError) instead of 3 (NXDOMAIN).

  - move reports of RRL drop and slip actions from the "queries"
     log category to the "query-errors" category. Because they are not
     in the "queres" category, enabling or disabling query logging no
     longer affects them.
