			when it should have. [GL !3880]

5473.	[func]		The rbt hashtable implementation has been changed
			to use faster hash-function (HalfSipHash2-4) and
			uses Fibonacci hashing for better distribution.
			Setting the max-cache-size now preallocates fixed
			size hashtable, so the rehashing doesn't cause
			resolution brownouts when growing the hashtable.

5467.	[func]		The control channel and the rndc utility have been
			updated to use the new network manager. To support
			this, the network manager was updated to enable
			wthe initiation of client TCP connections. Its
			internal reference counting has been refactored.

			Note: As side effects of this change, rndc cannot
			currently be used with UNIX-domain sockets, and its
			default timeout has changed from 60 seconds to 30.
			These will be addressed in a future release.

5373.	[bug]		Collecting statistics for DNSSEC signing operations
			(change 5254) caused an array of significant size (over
			100 kB) to be allocated for each configured zone. Each
			of these arrays is tracking all possible key IDs; this
			could trigger an out-of-memory condition on servers with
			a high enough number of zones configured. Fixed by
			tracking up to four keys per zone and rotating counters
			when keys are replaced. This fixes the immediate problem
			of high memory usage, but should be improved in a future
			release by growing or shrinking the number of keys to
			track upon key rollover events. [GL #1179]
