… with Mutex, avoid data race, partial bitcoin#22868 87d775d partial bitcoin#22868: Call load handlers without cs_wallet locked (Kittywhiskers Van Gogh) c602ca1 coinjoin: protect `m_wallet_manager_map` with `cs_wallet_manager_map` (Kittywhiskers Van Gogh) Pull request description: ## Additional Information This pull request aims to deal with regressions ([build](https://gitlab.com/dashpay/dash/-/jobs/7550859495)) spotted in `develop` after the merger of [dash#6143](#6143), namely, a failure to build the multiprocess variant and two data races, one involving `ChainstateManager::m_best_header` and another involving `CoinJoinWalletManager::m_wallet_manager_map`. * Fixes for the build failure and the first data race (b136742 and 9e7c685), have been spun off into [dash#6199](#6199) and merged * The second data race is being avoided by protected `m_wallet_manager_map` with a new `RecursiveMutex`, `cs_wallet_manager_map` (the contents of this PR). ~~A version of these changes are available using a regular `Mutex` but prove far more cumbersome ([source](b89457d)) when taking practicalities into account ([comment](#6192 (comment) A `Mutex` version is now available courtesy of UdjinM6 (see [patch](ecf5c1b)), thanks! ## Checklist: - [x] I have performed a self-review of my own code - [x] I have commented my code, particularly in hard-to-understand areas **(note: N/A)** - [x] I have added or updated relevant unit/integration/functional/e2e tests - [x] I have made corresponding changes to the documentation **(note: N/A)** - [x] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ ACKs for top commit: UdjinM6: light-ACK 87d775d Tree-SHA512: 52545a1547357a45fb6bf4d3948fc75a5e88f1d86e9809b1060007cd74dd383249691d8d9777f647c7534d458fe126ae818fa2b47f0e5b0cee78a469af1ed0c9
