description:
Import dhcpcd-8.0.3 With the following changes:
* DHCP: Work with IP headers with options
* script: Assert that env string are correctly terminated
* script: Terminate env strings with no value
* script: Don't attempt to use an invalid env string
* route: Fix NULL deference error when using static routes
* ARP: Respect IFF_NOARP
* DHCP: Allow full DHCP support for PtP interfaces, but not by default
* control: sends correct buffer to listeners
dhcpcd-ui now correctly reports SSD association and all the addresses obtained (regression from dhcpcd-7)
