Huge update! The big points are:

• ARP now supports many requests
• Routing tables now use Red-Black Trees
• Script variables are no longer allocated manually

dhcpcd-7 branch has now entered maintainance only mode, which means it only gets security updates. Minor changes from dhcpcd-7.2.3 include:

• DHCP addresses are added with vltime of the lease time and pltime of the rebind time (Linux only)
