[gimp/wip/nielsdg/string-array-to-strv: 388/390] Remove GimpStringArray in favor of GStrv




commit d036e5444f28c5112faa8df58b3271af9fe9511b
Author: Niels De Graef <nielsdegraef gmail com>
Date:   Wed Dec 23 21:15:43 2020 +0100

    Remove GimpStringArray in favor of GStrv
    
    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).
