Android Port

It is time for GNUnet to run properly on Android. Note that GNUnet is written in C, and this is not about rewriting GNUnet in Java, but about getting the C code to run on Android.

Help with Continuous Integration setup

There is a push for migrating our CI to Gitlab. The CI should eventually not just run "make check" on various platforms, but also perform tests with multiple peers running in different VMs with specific network topologies (i.e. NAT) between them being simulated. The CI should also be integrated with Gauger for performance regression analysis. Running jobs only when dependencies have changed and scripting more granular triggers or ideally automatic dependency discovery (as done by the autotools) is also important.

Migrate gnunet-qr from Python 2.7 to C using libzbar

Python 2.7 is reaching its end-of-life, and we want to get rid of the dependency on Python. The existing gnunet-qr tool is a rather simple wrapper around python-zbar, which itself wraps libzbar. The goal of this project is to directly use libzbar to scan QR codes for GNUnet / the GNU Name System (see also #5562).
