Update to 3.1.2

Changes since 3.1.2rc1
* None.

Changes since 3.1.2b1
* Fix handling of domain-search option to append "." as already done \ 
with 4.x.

Changes since 3.1.1
* A double-dereference in dhclient transmission of DHCPDECLINEs was repaired.
* Fix handling of -A and -a flags in dhcrelay; it was failing to expand packet \ 
size as needed to add relay agent options.
* Corrected list of failover state values in dhcpd man page.
* Fixed a bug that caused some request types to be logged incorrectly.
* Fixed a coredump when adding a class via OMAPI.
* Clients that sent a parameter request list containing the routers option \ 
before the subnet mask option were receiving only the latter. Fixed.
* The server wasn't always sending the FQDN option when it should.
* A partner-down failover server no longer emits 'peer holds all free leases' if \ 
it is able to newly-allocate one of the peer's leases.
* A cosmetic bug in DHCPDECLINE processing was fixed which caused all successful \ 
DHCPDECLINEs to be logged as "not found" rather than \ 
"abandoned".
* Some failover debugging #defines have been better defined and some high \ 
frequency messages moved to a deeper debugging symbol.
* The CLTT parameter in failover is now only updated by client activity, and not \ 
by failover binding updates (taking on the peer's CLTT).
* Failover BNDUPD messages are now discarded if they conflict with an update \ 
that has been trasnmitted, but not acknowledged.
* A bug cleaning up unknown-xxx temporary option definitions was fixed.

Changes since 3.1.1rc2
* None.

Changes since 3.1.1rc1
* Changes in 4.0.x to common/options.c "pretty_domain()" (which turns \ 
wireformat rfc1035 into printable form for dhclient.leases) were pulled down. \ 
This addresses a bug where "option domain-search , ;" would appear in \ 
dhclient.leases.
* Changes in 4.0.x to common/tables.c "option_dereference()" were \ 
pulled down. This addresses a bug where overlapping option code definitions in a \ 
config file may cause an attempt to free a NULL pointer.

Changes since 3.1.1b1
* A memory leak when using omapi has been fixed.
