Previously we were using ASSERT(0|false), which only works in debug
builds. In some cases, this is intended, but we cannot reliably continue
operation in others. We now use abort() where we have to terminate the
program abnormally. In cases where only debug builds should terminate, a
comment is added.
This is done along with the logging updates as the code is typically
related and would cause conflicts otherwise.
Closes: #163

Previously the maximum waiting time was just over 24 days. In a DTN
setup we may want to wait longer, e.g., for contacts to occur. This
allows for waiting about 292 years. If the provided delay exceeds this
threshold, an infinite delay is assumed.

We cannot easily support this on MacOS, but we do not use it except in
tests. Thus, remove it and make the tests only run on Linux and use
`sem_getvalue` directly.

Unnamed semaphores are unsupported there, which is why we were seeing
segfaults.

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.

As we are moving to `BSD-3-Clause OR Apache-2.0`, this needs to be
adapted as well. (We got the permission of Robert to publish his code
under the new licensing scheme.)
