This reworks sd-ndisc and networkd substantially to support IPv6 RA much more comprehensively. Since the API is extended quite a bit networkd has been ported over too, and the patch is not as straight-forward as one could wish. The rework includes: - Support for DNSSL, RDNSS and RA routing options in sd-ndisc and networkd. Two new configuration options have been added to networkd to make this configurable. - sd-ndisc now exposes an sd_ndisc_router object that encapsulates a full RA message, and has direct, friendly acessor functions for the singleton RA properties, as well as an iterative interface to iterate through known and unsupported options. The router object may either be retrieved from the wire, or generated from raw data. In many ways the sd-ndisc API now matches the sd-lldp API, except that no implicit database of seen data is kept. (Note that sd-ndisc actually had a half-written, but unused implementaiton of such a store, which is removed now.) - sd-ndisc will now collect the reception timestamps of RA, which is useful to make sd_ndisc_router fully descriptive of what it covers. Fixes: #1079
