Add support for adaptive icons
As detailed here, all existing Android apps need to target API 26 or higher in order to provide updates on Play Store from November 2018.
When an app targets API 26, unless it provides an adaptive icon the icon of the app is masked according to the shape chosen by the user which would translate into a small VLC icon against a white background in any of the adaptive icon shapes.
It would be nice to begin working on an adaptive icon for this eventuality. Additionally, an adaptive icon can be provided even without targeting API 26 by simply compiling with API 26. This means that once the icon is ready, it can be rolled out right away without waiting for all the other changes that need to be made in order to target API 26.
