Martin Holst Swende	40b6ccf383	core,les: headerchain import in batches (#21471) ... * core: add test for headerchain inserts * core, light: write headerchains in batches * core: change to one callback per batch of inserted headers + review concerns * core: error-check on batch write * core: unexport writeHeaders * core: remove callback parameter in InsertHeaderChain The semantics of InsertHeaderChain are now much simpler: it is now an all-or-nothing operation. The new WriteStatus return value allows callers to check for the canonicality of the insertion. This change simplifies use of HeaderChain in package les, where the callback was previously used to post chain events. * core: skip some hashing when writing headers * core: less hashing in header validation * core: fix headerchain flaw regarding blacklisted hashes Co-authored-by: Felix Lange <fjl@twurst.com>	4 years ago
