This avoids issues for parameter strings containing characters that are
treated specially while parsing the arguments, e.g. whitespace.

Instead of passing all parameters using the command line, we write them
first into a file and then pass the filename to the end-to-end
framework.

Use the new basic building blocks SwitchNode and SimpleChannel in the
ns3 end-to-end framework to build topologies.

This adds support for configuring and running simulations using the ns3
end-to-end framework.

Add all TCP congestion control algorithms that are currently available
in the kernel source tree as loadable modules.

This temporarily drops support for DDIO and the L3 cache.

The doc string says to return 1 in the case of an unnecessary sync, which the implementation actually doesn't do. It instead considers an unnecessary sync as success, which is generally also the intended behavior.

We already have a similar and much more detailed section in howto.rst. Further, the included run.py usage print will often be out-of-date and manually updating it every time isn't maintainable.

To manage external links such as for Python Modules, we are now using the extension sphinx.ext.extlinks to define all of them in the file doc/external_links.py.

ExpEnv hd_path and hd_path_raw use absolute path unmodified if given as param

Before this, if registry or tag got set, we would still build all images
starting from the docker hub regsitry version and latest tag.

This makes it easier for images that build on ours to use tools like packer
without having to specify the full path

Update to newer ns-3 version and adapt code for changes (mostly
renamed files and command line parameters) in the ns-3 submodule.

besides main time, print in and out timestamp for the ports' underlying SimBricks interfaces

besides main time, we now also print in and out timestamp of the underlying SimBricks interfaces

fix container, Python version, path to sphinx' conf.py and add all
required packages

Switch cloud-init data source from nocloud-net to nocloud, since
noncloud-net is now marked as deprecated and same functionality is
provided by nocloud.

Switch to an older release of the ubuntu minimal cloud image, because
the most recent version (20240222) introduced a bug that prevents the
base image from building.

Check the length of socket paths in SimbricksBaseIfListen and
SimbricksBaseIfConnect. If the length exceeds the size of sun_path in
the sockaddr_un struct, we fail with a meaningful error message.

This resolves #42.

This change is mostly about the default semantics of asyncio.wait(). It
doesn't forward any exceptions that are raised by any of the coroutines
it waits for. This effectively causes exceptions to be swallowed. In
contrast, asyncio.gather() forwards exceptions to its calling coroutine.
