			Changes since 4.1-ESV-R5b1

- None

			Changes since 4.1-ESV-R4

- Fixed the code that checks if an address the server is planning
 to hand out is in a reserved range.  This would appear as
 the server being out of addresses in pools with particular ranges.
 [ISC-Bugs #26498]

- Tidy up the receive calls and eliminate the need for found_pkt
 [ISC-Bugs #25066]

- Add support for Infiniband over sockets to the server and
 relay code.  We've tested this on Solaris and hope to expand
 support for Infiniband in the future.  This patch also corrects
 some issues we found in the socket code.  [ISC-Bugs #24245]

- Add a compile time check for the presence of the noreturn attribute
 and use it for log_fatal if it's available.  This will help code
 checking programs to eliminate false positives.
 [ISC-Bugs #27539]

- Fixed many compilation problems ("set, but not used" warnings) for
 gcc 4.6 that may affect Ubuntu 11.10 users. [ISC-Bugs #27588]

- Remove outdated note in the bootp keyword about the option not satisfying
 the requirement of failover peers for denying dynamic bootp clients.
 [ISC-bugs #28574]

- Multiple items to clean up IPv6 address processing.
 When processing an IA that we've seen check to see if the
 addresses are usable (not in use by somebody else) before
 handing it out.
 When reading in leases from the file discard expired addresses.
 When picking an address for a client include the IA ID in
 addition to the client ID to generally pick different addresses
 for different IAs.
 [ISC-Bugs #23138] [ISC-Bugs #27945] [ISC-Bugs #25586]
 [ISC-Bugs #27684]

- Remove unnecessary checks in the lease query code and clean up
 several compiler issues (some dereferences of NULL and treating
 an int as a boolean).
 [ISC-Bugs #26203]

- Fix the NA and PD allocation code to handle the case where a client
 provides a preference and the server doesn't have any addresses or
 prefixes available.  Previoulsy the server ignored the request with
 this patch it replies with a NoAddrsAvail or NoPrefixAvai respone.
 By default the code performs according to the errata of August 2010
 for RFC 3315 section 17.2.2, to enable the previous style see the
 seciton on RFC3315_PRE_ERRATA_2010_08 in includes/site.h.  This option
 may be removed in the future.
 Thanks to Jiri Popelka at Red Hat for the patch.
 [ISC-Bugs #22676]

- Fix up some issues found by static analysis
 A potential memory leak and NULL dereference in omapi.
 The use of a boolean test instead of a bitwise test in dst.
 [ISC-Bugs #28941]
