net/bind916: update to 9.16.25

Notes for BIND 9.16.25

Feature Changes

* Overall memory use by named has been optimized and reduced, especially on
  systems with many CPU cores.  The default memory allocator has been
  switched from internal to external.  A new command-line option -M internal
  allows named to be started with the old internal memory allocator.  [GL
  #2398]

Bug Fixes

* On FreeBSD, TCP connections leaked a small amount of heap memory, leading
  to an eventual out-of-memory problem.  This has been fixed.  [GL #3051]

* If signatures created by the ZSK were expired and the ZSK private key was
  offline, the signatures were not replaced.  This behavior has been amended
  to replace the expired signatures with new signatures created using the
  KSK.  [GL #3049]

* Under certain circumstances, the signed version of an inline-signed zone
  could be dumped to disk without the serial number of the unsigned version
  of the zone.  This prevented resynchronization of the zone contents after
  named restarted, if the unsigned zone file was modified while named was
  not running.  This has been fixed.  [GL #3071]
