creation call. It allows passing context information and an arbitrary user argument into
the message queue. Also streamlined and simplified `MessageQueue` implementation for all OSALs
PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/583
- Clock:
- `timeval` to `TimeOfDay_t`
- Added Mutex for gmtime calls: (compare http://www.opengate.at/blog/2020/01/timeless/)
- Moved the statics used by Clock in ClockCommon.cpp to this file
- Better check for leap seconds
- Added Unittests for Clock (only getter)
## Removed
