Hi List!

A long overdue release, and apologies for the wait
Fixed stuff:
  *  Added support for setproctitle(3)
  *  Kernel RA is no longer disabled when IPv6 is disabled in dhcpcd
  *  DHCPv6 PD is no longer stopped if no Routers are found
  *  If the DHCP leased address is deleted, enter the reboot state
  *  DHCPv6 unicast is no longer performed when not in master mode
  *  dhcpcd will now detect netlink/route socket overflows ad re-sync

The last point is the one that took sometime, mainly because I had to 
patch the NetBSD kernel on my router where this happens a lot when 
booting. Technically this was achieved just as in Linux - recv(2) now 
returns ENOBUFS when the internal receive buffer as overflowed. OpenBSD 
has a different approach where they flush the internal buffer and send a 
custom route(4) RTM_DESYNC message. This is supported as well.

Once overflowed, dhcpcd will close the socket to throw away now garbage 
messages and open a new one. Then it will re-learn interfaces (+ their 
carrier state and flags) and addresses (+ their flags and lifetimes). 
dhcpcd will then run the hooks for any 
departed/arrvied/carrier/nocarrier events resulting from this, in other 
words it should function as if nothing happened.
