fac04cb refactor: Add lock annotations to Active* methods (MacroFake) fac15ff Fix logical race in rest_getutxos (MacroFake) fa97a52 Fix UB/data-race in RPCNotifyBlockChange (MacroFake) fa530bc Add ChainstateManager::GetMutex(), an alias for ::cs_main (MacroFake) Pull request description: This fixes two issues: * A data race in `ActiveChain`, which returns a reference to the chain (a `std::vector`), which is not thread safe. See also below traceback. * A corrupt rest response, which returns a blockheight and blockhash, which are unrelated to each other and to the result, as the chain might advance between each call without cs_main held. The issues are fixed by taking cs_main and holding it for the required time. ``` ================== WARNING: ThreadSanitizer: data race (pid=32335) Write of size 8 at 0x7b3c000008f0 by thread T22
