* Fixed a segfault when configuring a static route in dhcpcd.conf
* Merged IPv6 ND and RA codebases
* Persistent configuration is now a default option in dhcpcd.conf
* Store configured IPv4 addresses against the interface so we only add
them if actually missing to avoid RTM_DELADDR/NEWADDR loops on some OS's
* waitip now supports waiting for any, IPv4, IPv6 or both protocols
* DHCPv6 addresses are added with a /128 prefix and should not attempt to
associate with any existing prefix or make one up as per RFC 5942
* Fix initial carrier status
* Fix requesting >1 DHCPv6 address
Fixes PR bin/48140
* DHCPv6 support
* wpa_supplicant hook script
* route IPv4 addresses to 127.0.0.1 for machine centric traffic
* DHCPv6 Prefix Delegation support
* DHCPv6 FQDN support
* Control existing IPv4 routes
* less spamy to syslog by default
* IPv6 protocols now wait for a valid LL address before starting
* IPv6 DAD support now listens to kernel for more accurate timings
* IPv4 code split out more cleanly so dhcpcd can be compiled for
IPv4, IPv6 or IPv4 AND IPv6
* MTU is no longer requested by default
* a DUID is now generated in /etc/dhcpcd.duid and this is used as a
client ID for DHCPv4 and DHCPv6
This does mean that you may get new DHCPv4 addresses
