d51d2a3bb5b0011efa1b4f1e2c9512a16ce9b347 scripted-diff: rename node vector/mutex members in CConnman (Sebastian Falbesoner)
574cc4271ab09a4c8f8d076cb1a3a2d5b3924b73 refactor: remove RecursiveMutex cs_totalBytesRecv, use std::atomic instead (Sebastian Falbesoner)
Pull request description:
This PR is related to #19303 and gets rid of the following RecursiveMutex members in class `CConnman`:
* for `cs_totalBytesRecv`, protecting `nTotalBytesRecv`, `std::atomic` is used instead (the member is only increment at one and read at another place, so this is sufficient)
* for `m_addr_fetches_mutex`, protecting `m_addr_fetches`, a regular `Mutex` is used instead (there is no chance that within one critical section, another one is called)
* for `cs_vAddedNodes`, protecting `vAddedNodes`, a regular `Mutex` is used instead (there is no chance that within one critical section, another one is called)
Additionally, the PR takes the chance to rename all node vector members (vNodes, vAddedNodes) and its corresponding mutexes (cs_vNodes, cs_vAddedNodes) to match the coding guidelines via a scripted-diff.
