Changes for dhcpcd:

  * BSD: don't send uninitialised memory using ps_root_indirectioctl
  * Fix fallback_time option
  * IPv4: Ignore DHCP state when building routes
  * route: Routes may not have an interface assinged
  * options: Ensure that an overly long bitflag string does not crash
  * options: Don't assume vsio options have an argument
  * common: Cast via uintptr_t rather than unsigned long in UNCONST
  * privsep: Ensure we recv for real after a successful recv MSG_PEEK
  * DHCP: Add parentheses to macro definitions
  * ipv6nd: empty IPV6RA_EXPIRE eloop queue when dropping
  * privsep: enforce message boundaries with MSG_EOR on our messages
  * Protocols will notify when dhcpcd can exit
  * DHCP: Don't request T1 and T2
  * DHCP: Don't request a lease time
  * DHCP6: Don't exit if using DHCP4 INFORM in non manager mode
  * ND: Route Information Option prefix is optional
  * ipv6: respect slaac hwaddr to really use the hwaddr
  * When stopping all interfaces at exit and releasing, remove persistance
  * NetBSD: Delete RTF_CONNECTED route when changing it
  * privsep: Drain the log when the root process is exiting
  * eloop: vastly reworked, kqueue and epoll support on by default
