low/high-watermark are of type double, and given in range 0.0-1.0. This makes it possible to set low/high watermarks with greater resolution, which is useful with large queue2 max sizes and watermarks like 0.5%. Also adding a test to check the fill and watermark level behavior. https://bugzilla.gnome.org/show_bug.cgi?id=769449
