This pull request groups together the set of commits that implements the new superblock validation. It is currently incomplete. This PR will track development of the integrated_scraper_2 through the conversion of the ValidateSuperblock function into a class.
It also includes the implemention of a "pending delete" map for CScraperManifests to avoid the occasional "spurious part" problems that we were seeing. We determined this was happening due to deletion of a manifest on the local node in between the request for a part based on that manifest and the actual receipt of the part by the node. If the manifest is deleted in between, a reference to the part may no longer exist and it will be deemed spurious. To prevent this, the CScaperManifest entry to be deleted is moved to the mapPendingDeletedManifest and held there for nScraperSleep time. Since the reference to the part is maintained, the part when received is no longer deemed spurious. nScraperSleep time is more than enough to deal with parts receipt latency.
