Also use some Spans where possible. - Remove useless CBlock::GetBlockHeader: There is no need for a function to convert a CBlock to a CBlockHeader, as it's a child class of it. It also contains the following code cleanups, which were suggested by reviewers in #25968: - Remove redundant parameter from CheckHeadersPoW: No need to pass consensusParams, as CheckHeadersPow already has access to m_chainparams.GetConsensus() - Remove unused parameter in ReportHeadersPresync - Use initializer list in CompressedHeader, also make GetFullHeader const - Use reference for chain_start in HeadersSyncState: chain_start can never be null, so it's better to pass it as a reference rather than a raw pointer *I decided to leave out three commits that were in #25968 (4e7ac7b94d,ab52fb4e95,7f1cf440ca), since they're a bit more involved, and I'm a new contributor. If this PR gets merged, I'll comment under #25968 to note that these three commits are still up for grabs :) ACKs for top commit: l0rinc: ACKde4242f474polespinasa: re-ACKde4242f474sipa: ACKde4242f474achow101: ACKde4242f474hodlinator: re-ACKde4242f474Tree-SHA512: 1de4f3ce0854a196712505f2b52ccb985856f5133769552bf37375225ea8664a3a7a6a9578c4fd461e935cd94a7cbbb08f15751a1da7651f8962c866146d9d4b
