The stackTrie is used to generate the merkle tree nodes upon receiving a state batch. Several additional options have been added into stackTrie to handle incomplete states (either missing states before or after). In this pull request, these options have been relocated from stackTrie to genTrie, which serves as a wrapper for stackTrie specifically for snap sync purposes. Further, the logic for managing incomplete state has been enhanced in this change. Originally, there are two cases handled: - boundary node filtering - internal (covered by extension node) node clearing This changes adds one more: - Clearing leftover nodes on the boundaries. This feature is necessary if there are leftover trie nodes in database, otherwise node inconsistency may break the state healing. ✖ body's lines must not be longer than 100 characters [body-max-line-length] ✖ header must not be longer than 80 characters, current length is 94 [header-max-length] ✖ found 2 problems, 0 warnings ⓘ Get help: https://github.com/bnb-chain/bsc/tree/develop/docs/lint/commit.md
