…p routines (#3342) We speedup the gossip routines by using caches for LoadBlockPart, and making LoadBlockCommit no longer call Clone, as the caller does read-only operations to it. This is a followup to #3003 This results in a net performance improvement, based on a 2hr sync on latest osmosis release, of: - 20% less RAM allocated over program lifetime. (76GB no longer allocated, 380 GB alloc total) - 50% speedup to gossipDataRoutine - ~10% speedup to gossipVotesRoutine - 1% less overall system CPU usage. (If GC proportional to bytes allocated, then 5% less) I have checked that every usage of `LoadBlockPart` and `LoadBlockCommit` do not modify the return value, so returning this underlying cache copy is safe for the current codebase I used an `!` in the title, since this is technically API breaking, even though all current usages are safe. --- #### PR checklist - [ ] Tests written/updated - [ ] Changelog entry added in `.changelog` (we use [unclog](https://github.com/informalsystems/unclog) to manage our changelog) - [ ] Updated relevant documentation (`docs/` or `spec/`) and code comments - [ ] Title follows the [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) spec (cherry picked from commit 2c88a26)
