Embed Prefix-SID information inside SPF data structures so that Prefix-SIDs can be installed together with their associated routes at the end of the SPF algorithm. This is different from the current implementation where Prefix-SIDs are parsed and processed separately, which is vastly suboptimal. Advantages of the new code: * No need to parse the LSPDB an additional time to detect and process SR-related changes; * Routes are installed with their Prefix-SID labels in the same ZAPI message. This can prevent packet dropping for a few milliseconds after each SPF run if there are BGP-labeled routes (e.g. L3VPN) that recurse on IGP labeled routes; * Much easier to support Anycast-SIDs, as the SPF code will naturally figure out the best nexthops and use only them (that can't be done in any reasonable way if the Prefix-SID Sub-TVLs are processed separately); * Less code to maintain and reduced memory footprint; The "show isis segment-routing prefix-sids" command was removed as it doesn't make sense anymore now that "show isis route" exists. Prefix-SIDs are a property of routes, so what was done was to extend the "show isis route" command with a new "prefix-sid" option that changes the output table to show the Prefix-SID information associated to each route.
