### Task Module Refactoring
PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/636
**Refactoring general task code**
- There was a lot of duplicate/boilerplate code inside the individual task IF OSAL implementations.
Remove it by introducing base classes `PeriodicTaskBase` and `FixedTimeslotTaskBase`.
**Refactor PeriodicTaskIF**
- Convert `virtual ReturnValue_t addComponent(object_id_t object)` to
`virtual ReturnValue_t addComponent(object_id_t object, uint8_t opCode = 0)`, allowing to pass
the operation code passed to `performOperation`. Updated API taking
an `ExecutableObjectIF` accordingly
**Refactor FixedTimeslotTaskIF**
- Add additional `addSlot` function which takes an `ExecutableObjectIF` pointer and its Object ID
**Refactor FixedSequenceSlot**
- Introduce typedef `CustomCheckFunc` for `ReturnValue_t (*customCheckFunction)(const SlotList&)`.
- Convert `ReturnValue_t (*customCheckFunction)(const SlotList&)` to
`ReturnValue_t (*customCheckFunction)(const SlotList&, void*)`, allowing arbitrary user arguments
for the custom checker
**Linux Task Module**
- Use composition instead of inheritance for the `PeriodicPosixTask` and make the `PosixTask` a
member of the class
### HAL
- HAL Linux Uart: Baudrate and bits per word are enums now, avoiding misconfigurations
