Assorted fixes for broken network devices: IP header length field is now
determined from payload, because some NIC drivers return more data than
they actually recived; IP and UDP packets now stored in aligned data
structures; outgoing packet TTL increased from 16 to 128. [rt15583]
A new server config option "fqdn-reply" specifies whether the server
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]

- The server's "by client-id" and "by hardware address" hash table lists
are now sorted according to the preference to re-allocate that lease to
returning clients. This should eliminate pool starvation problems
arising when "INIT" clients were given new leases rather than presently
active ones. [ISC-Bugs #16831]

- Some bugs were fixed in the 'emergency relay agent options hologram'

client was in INIT or REBIND states. This should solve problems where
relay agent options were not echoed from the server, even when giaddr

- In the case where an "L2" DHCP Relay Agent (one that does not set giaddr)
was directly attached to the same broadcast domain as the DHCP server,
the RFC3046 relay agent information option was not being returned to the
relay in the server's replies. This was fixed; the dhcp server no longer
requires the giaddr to reply with relay agent information. Note that
this also improves compatibility with L2 devices that "intercept" DHCP
packets and expect relay agent information even in unicast (renewal)
replies. [ISC-Bugs #16762]

- Some default hash table sizes were tweaked, some upwards, some downwards.
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.

- 'ignore client-updates;' now has behaviour that is different from
'deny client-updates;'. The client's request is not truly ignored,
rather it is encouraged. Should this value be configured, the server
updates DNS as though client-updates were set to 'deny'. That is, it
enters into DNS whatever it is configured to do already, provided it is
configured to. Then it sends a response to the client that lets the
client believe it is performing client updates (which it will), probably
for a different name. In essence, this lets the client do as it will,
ignoring this aspect of their request. [ISC-Bugs #16185]
