* IAID must be inside an interface block.
* Detect IPv6 address flags on Linux.
* Check that we have ctrl_interface defined in wpa_supplicant.conf and pass this parameter to wpa_cli(8). If not set, warn about not interacting with wpa_supplicant(8).
* Skip Virtual Interface Masters. Currently this only applies to FreeBSD VAP masters as dhcpcd should only work on wlandev created clones.
* Fix handling of ARP failures, thanks to Sebastian Huber.
* Implement RFC 1321 MD5 Message-Digest if not provided in libc.
* Implement RFC 2104 HMAC Keyed Hashing.
* Implement RFC 3118 Authentication for DHCP Messages and RFC 3315 Authentication options.
* Add nodhcp and nodhcp6 directives. Thanks to Sebastian Huber for the initial patch and testing.
* Implement support for RFC 3203, FORCERENEW message.
* Implement Force Renew Nonce Capability option, RFC6704
* Support RECONFIGURE DHCPv6 messages.
* Add support for DHCP auto configuration, RFC 2563.
* Add support for the following RFCs
+ DHCP SLP Directory Agent, RFC2610
+ DHCP Name Service Search, RFC2937
+ DHCP PANA Authentication Agent, RFC5192
+ DHCP Lost Server, RFC5223
+ DHCP CAPWAP, RFC5417

+ DHCPv6 Relay-ID, RFC5460
+ DHCPv6 LIS Discovery, RFC5986
+ DHCPv6 SIP UA, RFC6011
+ DHCPv6 Network Boot, RFC5970
+ DHCPv6 Home Info Discovery in MIPv6, RFC6610
+ DHCPv6 RDNSS Selection for MIF Nodes, RFC6731
+ DHCPv6 Kerberos, RFC6784
+ DHCPv6 Relay-Triggered Reconfiguration, RFC6977
+ DHCPv6 SOL_MAX_RT, RFC7083
* Open UDP sockets for *.*.*.*:bootpc and $ip_address:bootpc to avoid kernel ICMP unreachable messages
* Moved global variables into context variables so dhcpcd is entirely thread safe.
dhcpcd doens't use threads, but it can now be used in a pure threads (ie no process) environment.
* Remove DEBUG_MEMORY guard and always free memory and resources. Remove all atexit(3) and exit(3) calls, instead exiting via the eloop.
* Replace get_line with sscanf where applicable.
* Remove custom set_cloexec and set_nonblock functions. Instead pass O_CLOEXEC or SOCK_CLOEXEC to open, socket, etc.
* Don't use PATH_MAX - we already know the maximum length from the initial directory and IF_NAMESIZE.
* Add a USE_SIGNALS define. If we're not using signals then we also create a control socket in the non MASTER case. We then use this to communicate instead of signals.
* Fix arping moving to the next test if we find the IP address but do not have a profile for it. Thanks to David McGurty for the analysis.
* Respect initial commandline arguments when rebooting via a signal.
