ea36796f82 [v9_9] DDoS mitigation features 
3938.	[func]		Added quotas to be used in recursive resolvers
			that are under high query load for names in zones
			whose authoritative servers are nonresponsive or
			are experiencing a denial of service attack.

			- "fetches-per-server" limits the number of
			  simultaneous queries that can be sent to any
			  single authoritative server.  The configured
			  value is a starting point; it is automatically
			  adjusted downward if the server is partially or
			  completely non-responsive. The algorithm used to
			  adjust the quota can be configured via the
			  "fetch-quota-params" option.
			- "fetches-per-zone" limits the number of
			  simultaneous queries that can be sent for names
			  within a single domain.  (Note: Unlike
			  "fetches-per-server", this value is not
			  self-tuning.)
			- New stats counters have been added to count
			  queries spilled due to these quotas.

			These options are not available by default;
			use "configure --enable-fetchlimit" (or
			--enable-developer) to include them in the build.

			See the ARM for details of these options. [RT #37125]

c2d3d0eda5 [v9_9] add no-case-compress 
3731.	[func]		Added a "no-case-compress" ACL, which causes
			named to use case-insensitive compression
			(disabling change #3645) for specified
			clients. (This is useful when dealing
			with broken client implementations that
			use case-sensitive name comparisons,
			rejecting responses that fail to match the
			capitalization of the query that was sent.)

This incorporates the following changes, plus a new configure
option "--enable-rrl" to turn them on:

3575.	[func]		Changed the logging category for RRL events from
			'queries' to 'query-errors'. [RT #33540]

3554.	[bug]		RRL failed to correctly rate-limit upward
			referrals and failed to count dropped error
			responses in the statistics. [RT #33225]

3545.	[bug]		RRL slip behavior was incorrect when set to 1.
			[RT #33111]

3518.	[bug]		Increase the size of dns_rrl_key.s.rtype by one bit
			so that all dns_rrl_rtype_t enum values fit regardless
			of whether it is teated as signed or unsigned by
			the compiler. [RT #32792]

3494.	[func]		DNS RRL: Blunt the impact of DNS reflection and
			amplification attacks by rate-limiting substantially-
			identical responses. To enable, use "configure
			--enable-rrl". [RT #28130]
