c2fef74ea9 bundle: Allow 64-bit bundle payload lengths
The bundle block length, fragment offset, and total ADU length fields
were using 32-bit uint types, effectively reducing the maximum bundle
payload size to 4 GiB. This changes the field types to 64-bit uint, so
we can support larger bundles.

2dcc1387eb bundle6/serializer: Replace flow control in macro with condition var
The previous version may lead to hard-to-spot issues later on.

e8a319a277 TX: Allow the bundle serializers to indicate failure if CLA fails
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.

298431c68f Insert SPDX license expression comments into our .c, .h, .py, and .sh code
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.

2a981e86e2 Change DTN timestamp to milliseconds
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 renames the enum and its two constants `UPCN_OK` and `UPCN_FAIL`
accordingly.
