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.

This adds a custom header that does explicitly not include the Unity
wrappers for malloc, free, etc. by defining the guard used by that header
file. This way we can remove the wrappers provided via the linker
altogether.

The node and service number are 64 bit unsigned integers. This fixes the
validation and EID serialized size calculation and adds appropriate
tests to the serializer unit tests.

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.

The BPv7 implementation was still using uin32_t for the node and service
numbers in ipn EIDs in several places.

In order to verify the correctness of bundle age block
de-/serialization, an unit test is added.

To be compatible with the latest version of BPv7, the internal
representation of DTN timestamps, for both uD3TN and the Python library,
is changed to milliseconds.
For compatibility reasons, a conversion to seconds is performed during
the de-/serialization of BPv6.
Furthermore, additional test cases are added and the creation_time_ms of
the test bundle is set to a non-trivial timestamp.
Also, the Python functions for converting POSIX timestamps to DTN
timestamps are removed, as there is now a distinction between BPv6 and
BPv7 DTN timestamps. The conversion is now done in the corresponding BP
implementations themselves.

This is the initial commit for uD3TN. uD3TN is a fork of uPCN v0.8.0,
which will be developed and maintained in a public Git repository.
