This commit contains some parts of https://github.com/ton-blockchain/ton/tree/accelerator This is auxiliary code that mostly does not change node behavior. 1) Semiprivate overlays and other improvements in overlays code 2) Rename actual_min_split -> monitor_min_split, fix building shard overlays 3) Loading block candidates by block id from DB, fix accept_block after validator restart 4) Cells: ProofStorageStat and changes in CellUsageTree 5) Remove some unused code, other minor changes
