Replace BusyBox udhcpc6 with OpenWrt's odhcp6c for improved DHCPv6 functionality and better integration with Router Advertisements (RA). The primary motivation is support for a common ISP deployment scenario where IPv6 addresses are assigned via SLAAC (from Router Advertisements) and DHCPv6 is used in stateless/information-only mode to provide DNS servers and other configuration options. This hybrid RA+DHCPv6 setup is standard practice for many ISPs but was not supported by udhcpc6, which treats RA and DHCPv6 as separate, non-integrated mechanisms. Additional benefits of odhcp6c: - Better IPv6 Prefix Delegation (IA-PD) support with proper handling of delegated prefix lifetimes and renewal - Native integration of RA-provided configuration (DNS servers, routes, addresses) with DHCPv6-provided options - Support for stateless DHCPv6 via information-only mode To verify stateless DHCPv6 integration with SLAAC addresses - the ISP scenario that motivated this migration, a new test case has been added.
