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.
[GL #1775]
5472. [func] The statistics channel has been updated to use the
new network manager. [GL #2022]

- None.
- BIND's cache database implementation has been updated to use a faster
hash-function with better distribution. In addition, the effective
max-cache-size (configured explicitly, defaulting to a value based on system
memory or set to 'unlimited') now pre-allocates fixed size hash tables. This
prevents interruption to query resolution when the hash tables need to be
increased in size. [GL #1775]
