PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/671 PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/671
- Improvements for `AcceptsTelemetryIF` and `AcceptsTelecommandsIF`:
- Make functions `const` where it makes sense
- Add `const char* getName const` abstract function
PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/684
- Move some generic `StorageManagerIF` implementations from `LocalPool` to
interface itself so it can be re-used more easily. Also add new
abstract function `bool hasDataAtId(store_address_t storeId) const`.
PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/685
## CFDP
- Refactoring of CFDP stack which was done during implementation of the CFDP source and destination
handlers.
- New filesystem module, changes for filesystem abstraction `HasFileSystemIF` to better
fit requirements of CFDP
- New `HostFilesystem` implementation of the `HasFileSystemIF`
- New `cfdp::UserBase` class which is the abstraction for the CFDP user in an OBSW context.
- mib module for the CFDP stack
- PDU classes renamed from `...Serializer`/`...Deserializer` to `...Creator`/`...Reader`
respetively
- Renamed `TcDistributor` to `TcDistributorBase` to prevent confusion
- Refactored `TcDisitributorBase` to be more flexible and usable for CFDP distribution
- Renamed `CCSDSDistributor` to `CcsdsDistributor` and add feature which allows it
to remove the CCSDS header when routing a packet. This allows CCSDS agnostic receiver
implementation without an extra component
