This introduces a JSON contact configuration format for the
deterministic first-contact forwarding (DFCF) implementation as a modern
alternative to our homebrewn configuration messages. For now, it is only
supported in the external DFCF BDM, but integration into the "router
agent" is planned.
Example JSON configuration string (from our tests):
```
{
"command": "ADD",
"node_id": "dtn://ud3tn2.dtn/",
"cla_addr": "mtcp:127.0.0.1:4223",
"reachable_eids": [
"ipn:1.0"
],
"contact_list": [
{
"start": 1401519306972,
"end": 1401519316972,
"data_rate": 2400,
"reachable_eids": [
"dtn://66553/",
"dtn://89326/"
]
},
{
"start": 1401519506972,
"end": 1401519516972,
"data_rate": 1200,
"reachable_eids": [
"dtn://12349/",
"dtn://89326/"
]
}
]
}
```
Closes: #15

This also extends the MTCP sink script to allow writing to stdout so we
can check the returned payload.

Former releases of uD3TN have included support for STM32/FreeRTOS.
Having this support from the first moment on was a good thing in
order to optimize for platforms with limited resources. As this
platform is not used in current uD3TN setups and as it results in quite
some maintenance work, it is removed with this commit. The removed parts
cover the implementation itself, tests, tools, documentation, parts of
the build/make scripts as well as licensing information.

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.

This commit remedies the issue of having to modifiy the bundle7.py before
being able to run the automated ION interoperability test by introducing
the --compatibility switch to bibe_over_mtcp_test.py. This command line
argument forces the generated BIBE bundle to use the administrative
record type code 7 instead of 3, ensuring compatibility to ION'S BIBE
implementation.

Changed default value of --outer from dtn://ud3tn.dtn to
dtn://lower.dtn, to match the description in the BIBE documentation.

This commit renames the --outer_destination and --inner_destination
commandline parameters to --outer and --inner respectively. It also
adds short forms (-o and -i).

The default port the script connected to was 4222 instead
of the mtcp port (4224). Also the destinations of the inner and outer
bundles were hardcoded and not changeable via commandline parameters.
This commit fixes those issues by changing the default port and adding
the outer_destination and inner_destination commandline arguments.

To effectively test whether reception and parsing of BIBE administrative
records work, a script for sending bundles containing dummy data is
needed.
This commit adds a simple python script for sending BPDUs to a local
uD3TN instance.

To distribute the pyD3TN DTN protocol implementations as well as the
uD3TN python utilities on PyPi, the Python code is organized in separate
directories and the PyPi packaging guideline is applied. The
restructuring also requires an adjustment of the imports in the scripts
in tools/ and test/.

This changes the core component name as well as the output binary names
(including the library and test binaries) from "upcn" to "ud3tn".
Additionally, the default configuration for the created socket and the
used EID is adapted.
