This PR adds the packet stack for the CCSDS File Delivery Protocol.
It also refactors the existing TMTC infastructure to allow sending
of CFDP packets to the CCSDS handlers.

This includes the whole PDU (Protocol Data Unit) stack:

  • File Data PDUs

and all file directive PDUs

  • ACK PDU
  • NAK PDU
  • Metadata PDU
  • Finished PDU
  • Prompt PDU
  • Keep Alive PDU
  • EOF PDU

The PR includes a full set of unittests for the packet stack
with a coverage of 90+ %.

The refactoring of the existing TMTC infastructure includes non-ideal
solutions like diamond inheritance.
Avoiding this solution would require refactoring the packet stack.
This would be a good idea anyway because the existing stack is tightly
coupled to the FSFW, making reuse more difficult if only the stack is
planned to be used without the store functionalities etc.

The PDU implementation provided here is only weakly coupled to the FSFW,
only using components like returnvalues or the Serialization modules.
There are dedicated serializers and deserializers, which also helps in
creating small focused modules which are easy to test.

Some of the modules here were provied by Matthias Tompert.

UartComIF: set O_NONBLOCK in canonical mode 
When using the non-canonical mode, the file descriptor can be opened
in blocking mode because the VTIME and VMIN termios parameters are
used to configure non-blocking mode. However, in canonical mode, the fd needs to be opened with O_NONBLOCK

Possible bugfix in DHB 
The delayCycles variables needs to be initialized differently
for periodic replies.
It is initialized to the maxDelayCycles value now
