GLib has a specific type of NULL-terminated string arrays: `G_TYPE_STRV`, which is the `GType` of `char**` aka `GStrv`. By using this type, we can avoid having a `GimpStringArray` which is a bit cumbersome to use for both the C API, as well as bindings. By using `GStrv`, we allow other languages to pass on string lists as they are used to, while the bindings will make sure to do the right thing. In the end, it makes the API a little bit simpler for everyone, and reduces confusion for people who are used to working with string arrays in other C/GLib based code (and not having 2 different types to denote the same thing).
