Snap sync accounts healing (#1225) * Added inspect module why: Find dangling references for trie healing support. details: + This patch set provides only the inspect module and some unit tests. + There are also extensive unit tests which need bulk data from the `nimbus-eth1-blob` module. * Alternative pivot finder why: Attempt to be faster on start up. Also tying to decouple pivot finder somehow by providing different mechanisms (this one runs in `single` mode.) * Use inspect module for healing details: + After some progress with account and storage data, the inspect facility is used to find dangling links in the database to be filled nose-wise. + This is a crude attempt to cobble together functional elements. The set up needs to be honed. * fix scheduler to avoid starting dead peers why: Some peers drop out while in `sleepAsync()`. So extra `if` clauses make sure that this event is detected early. * Bug fixes causing crashes details: + prettify.toPC(): int/intToStr() numeric range over/underflow + hexary_inspect.hexaryInspectPath(): take care of half initialised step with branch but missing index into branch array * improve handling of dropped peers in alternaive pivot finder why: Strange things may happen while querying data from the network. Additional checks make sure that the state of other peers is updated immediately. * Update trace messages * reorganise snap fetch & store schedule 2022-09-16 08:24:12 +01:00			`# Nimbus`
