Unify SolarMutex implementations
All backends implement the SolarMutex in mostly the same way. So this consolidates this code into a GenericSolarMutex. We still need the abstract SolarMutex class for the fake AKA fascade implementation in dbaccess. The patch also replaces various places of direct mutex usage with either SolarMutexGuard or SolarMutexReleaser objects.
