odhcpd: add a full and ipv6only variant (FS#1188)

Add an ipv6only variant providing server services for RA, stateful and stateless
DHCPv6, prefix delegation and relay support for DHCPv6, NDP and RA.

The full variant called odhcpd supports DHCPv4 server as before.

  odhcpd is a daemon for serving and relaying IP management protocols to
  configure clients and downstream routers. It tries to follow the RFC 6204
  requirements for IPv6 home routers.
- 
- odhcpd provides server services for DHCP, RA, stateless and stateful DHCPv6,
- prefix delegation and can be used to relay RA, DHCPv6 and NDP between routed
- (non-bridged) interfaces in case no delegated prefixes are available.
