    Also updated dhcp/.gitignore

Add support to set high and low thresholds for pools for
v4 and v6.  A message will be emitted when the usage of
the pool first exceeds the high threshold.  More messages
will be skipped until the usage has gone below the low
threshold and then back above the high threshold.

    Remove old information from copyrights and
    man pages.

This patch adds an option to allow the administrator to tell the
server to ignore UIDS when choosing a lease.

The option is dont-use-async <flag> and it defaults to disabled.

Add code to support the standards version of DDNS

  has elapsed (default 25%), the server will reuse the allocated lease
  (provide a lease within the currently allocated lease-time) rather
  than extend or renew the lease.  This absolves the server of needing
  to perform an fsync() operation on the lease database before reply,
  which improves performance. [ISC-Bugs #22228]

  Brian Masney and S.Kalyanasundraram and maintained for application to
  the DHCP-4 sources by David Cantrell has been included.  Please be
  advised that these sources were contributed, and do not yet meet the
  high standards we place on production sources we include by default.
  As a result, the LDAP features are only included by using a compile-time
  option which defaults off, and if you enable it you do so under your
  own recognizance.  We will be improving this software over time.

for new web site as appropirate.

  This feature is simply too experimental for right now, and causes
  some problems to some failover installations.  We will revisit this
  in future releases.  [ISC-Bugs #18832]

  fsync()'s, it can be configured by the max-ack-delay configuration
  parameter.  [ISC-Bugs #17679]

  released in bursts after single fsync() events when the upper limit is
  reached or if the receiving sockets go dry.  The practical upshot is
  that fsync-coupled server performance is now multiplicitively increased.
  The default delayed ack limit is 28.  Thanks entirely to a patch from
  Christof Chen.

  broke a lot of legacy site local configurations.  The new code in place will
  track site local space minimum option codes and logs a warning to encourage
  updates and exploration of site local code migration problems.  Option
  codes less than 128 in site local spaces remain inaccessible.

- A possible relay agent option bug was repaired where random server
  initialization state may have been used to signal the relay agent
  information options sub-option code for the 'END' of the option space.

should send out option 81 (FQDN).  Defaults to "on".  If set to "off",
the FQDN option is not sent, even if the client requested it.  This is
needed because some clients misbehave otherwise. [rt16624]

  which causes the server to abstain from performing updates on PTR

  fatal internal error, "Unable to find server option 49". [ISC-Bugs #16566]

  3.1.0a1's tables resulted in a reduction in default server memory use.
  The new selected values provide more of a zero sum (increasing the size
  of tables likely to be populated, decreasing the size of tables unlikely).

- Lease structures appear in three spearate hashes: by IP address, by UID,
  and by hardware address.  One type of table was used for all three, and
  improvements to IP address hashing were applied to all three (so UID and
  hardware addresses were treated like 4-byte integers).  There are now two
  types of tables, and the uid/hw hashes use functions more appropriate
  to their needs.

- The max-lease-misbalance percentage no longer causes scheduled rebalance
  runs to be skipped: it still governs the schedule, but every scheduled
  run will attempt balance.
