This makes µD3TN behave the same as v0.13.0 when executed without an
additional commandline argument. A new commandline argument `-d` /
`--external-dispatch` is added, which enables the use of external BDMs.
The default forwarding implementation is now again provided using the
v0.13 code, extracted from e1621765a4 and
adapted to the new agent-based forwarding implementation.
Central changes to the old code include:
- A new "Routing Agent" that handles incoming configuration commands,
FIB updates, and BDM dispatch requests.
- The use of the BDM authorization flag to authorize contact
configuration commands.
- The Contact Manager now only triggers the creation and removal of
links / FIB entries; bundle dispatch is triggered through the FIB and
BDM callback functions of the Routing Agent.
- The fragmentation logic is adapted to store the original bundle along
with an offset and length value, instead of pre-creating and storing
the fragments.
- The bundle re-scheduling logic integrated into the Routing Agent is
simplified and does not support changing the fragmentation parameters.
A new function is added to the Router that searches for a new route
for such fragments that were already scheduled at some point,
considering them as un-fragmentable bundle with overridden fragment
offset and length.
