Relicensing project to Apache License 2.0 (or MIT)

The default COVESA license is Mozilla Public License v 2.0 (MPLv2) because it provides a good balance between wide adoption and a copyleft effect that reduces risk of privatization of the code base by any party at a later time (see COVESA license policy).

There are however occasionally concerns when tools perform some sort of code-generation. There _may_ be implementation choices that includes some part (or derivative thereof) of the tool source code in the generated result. Even if MPLv2 is generally considered a _weak_ copyleft license, and seems unlikely to intend to have that effect on generated code, it is still desirable by some companies to see a permissive license for tools of this nature.

The [Apache License v2.0](https://apache.org/licenses/LICENSE-2.0) is a popular permissive license alternative, because of the other conditions that are included.

Therefore, the IFEX project is now exploring the possibility to relicense the project. This ticket tracks the progress.

Start by reviewing the COVESA license policy referenced in the issue and the Apache License 2.0 linked there. The issue does not name files or tests; completion would require an agreed project-wide relicensing decision and a defined implementation plan.
