This enables AAP 2.0 clients to receive status reports with a new ADU
flag (as we already deliver BIBE bundles). Moreover, it allows clients
to set a report-to EID and sets all of the status report flags on newly
created bundles in case a report-to EID is provided.

This adds a `bundle_is_valid` function checking for further MUST
constraints defined by the spec., which further processing inside uD3TN
may depend on.

If the write method of the CLA fails, the serailizers will now return
early and this failure is handled properly by the TX task.
In the case of the BPv6 serializer, we add the necessary flow control to
the `write_bytes` macro, to prevent needing a conditional for every
write* or serialize* statement.

Previously the fragmentation logic was very specific to uD3TN's
forwarding approach, modifying the original bundle in the process. With
BDMs supporting fragmentation we must make this more flexible. Thus, we
now pass an offset and length and always create a copy of the required
contents based on the original bundle.

This also adds a test for it, sending bundles from within ION to uD3TN
in the "minimal forwarding test".

ud3tn is available under multiple licenses and we want to reflect this in
our source code. But which license information should appear first and how
can we manage this efficiently in the future? The Linux Kernel uses SPDX
expressions instead of boilerplate sections. This seems to be a great
approach, so we do the same here.

Based on a contribution by @mnitsch, 351e1dae9.
This removes `hal_*` dependencies in the bundle processing components,
with the goal that these parts can be re-used without depending on the
uD3TN core functions and underlying system state. The required variables
are passed as function arguments from the uD3TN core components.

This adds the bundle sequence number as an argument to the bundle
creation functions and passes a sequence number which increases when
multiple bundles are generated by the application agent with the same
creation timestamp.

The re-name to "enum ud3tn_result" broke the indentation in some
function signatures, which is fixed by this commit.
