Changes since 9.5.0.

	--- 9.5.3rc1 released ---

2946.	[doc]		Document the default values for the minimum and maximum
			zone refresh and retry values in the ARM. [RT #21886]

2945.	[doc]		Update empty-zones list in ARM. [RT #21772]

2944.	[maint]		Remove ORCHID prefix from built in empty zones.
			[RT #21772]

2937.	[bug]		Worked around an apparent race condition in over
			memory conditions.  Without this fix a DNS cache DB or
			ADB could incorrectly stay in an over memory state,
			effectively refusing further caching, which
			subsequently made a BIND 9 caching server unworkable.
			This fix prevents this problem from happening by
			polling the state of the memory context, rather than
			making a copy of the state, which appeared to cause
			a race.  This is a "workaround" in that it doesn't
			solve the possible race per se, but several experiments
			proved this change solves the symptom.  Also, the
			polling overhead hasn't been reported to be an issue.
			This bug should only affect a caching server that
			specifies a finite max-cache-size.  It's also quite
			likely that the bug happens only when enabling threads,
			but it's not confirmed yet. [RT #21818]

2420.	[bug]		Windows socket handling cleanup.  Let the io
			completion event send out cancelled read/write
			done events, which keeps us from writing to memory
			we no longer have ownership of.  Add debugging
