069282611c refactor: make CActiveMasternodeManager::cs SharedMutex and private (pasta)
663774c544 feat: implement Read Write Locks in threading (pasta)
Pull request description:
## Issue being fixed or feature implemented
We have some caches or other information in codebase which are read from a lot; but rarely written to. We can use a RW lock here instead of a normal Mutex
## What was done?
Implement a RW lock and use them
## How Has This Been Tested?
Hasn't been much; looking for review atm. Maybe should deploy this on testnet for a bit and make sure it doesn't break.
