Migrate from intltool to gettext intltool has long been dead upstream. Let's not poke the dead corpse, please. This commit is quite large, but that's mostly since trying to support a hybrid of both gettext and intltool with both Meson and Autotools was really hard, so I stopped trying. Due to gettext relying on quite some things being at the exactly right place in the autotools build (like `ABOUT-NLS` and `config.rpath`) we really needed to cleanup the `autogen.sh` to only call `aclocal` and `autoreconf`. No more strange magic; I tried to do it without changing too much in the file, and things just broke. If people want to do something more custom, they can just change the script directly. This change also uncovered some problems in our `configure.ac`, like using deprecated macros. The following major changes happened: * meson: Changed `custom_target()` to `i18n.merge_file()` for all supported file types * Added `.its` and `.loc` files for the GIMP-specific XML formats, so that gettext understands them * For the `.isl` (Window installer stuff) file, there's no easy way to do this in gettext, so instead we start from an XML file (again with its own ITS rules etc), translate that with gettext, and then use `xsltproc` with a bit of magic to output the .isl file for each language * the `po*/Makefile.in.in` files are migrated to `Makevars` files, which gettext natively understands.
