65a01b7 Tidy address-union handling: move class into explicit argument.
bde4647 Tidy all_addr union, merge log and rcode fields.
e7bfd55 Alter DHCP address selection after DECLINE in consec-addr mode. Avoid offering the same address after a recieving a DECLINE message to stop an infinite protocol loop. This has long been done in default address allocation mode: this adds similar behaviour when allocaing addresses consecutively.

The most relevant fix for openwrt is 18eac67 (& my own local f52bb5b
which fixes a missing bracket silly) To quote the patch:

It is possible for a config entry to have one address family specified by a
dhcp-host directive and the other added from /etc/hosts. This is especially
common on OpenWrt because it uses odhcpd for DHCPv6 and IPv6 leases are
imported into dnsmasq via a hosts file.

To handle this case there need to be separate *_HOSTS flags for IPv4 and IPv6.
Otherwise when the hosts file is reloaded it will clear the CONFIG_ADDR(6) flag
which was set by the dhcp-host directive.

Subject: [PATCH 16/30] build failure on master with NO_DHCPv6 and fix....
Hi Simon,
master has a build error when building without HAVE_DHCPv6
option.c: In function 'dhcp_context_free':
option.c:1042:15: error: 'struct dhcp_context' has no member named 'template_interface'
free(ctx->template_interface);
Sadly, need to put in a little conditional compilation ifdef'erey
Simplest patch in the world attached
Cheers,
Kevin D-B
