That’s what xdgmime uses for zero-sized files (see `XDG_MIME_TYPE_EMPTY`).
Historically, GLib explicitly used `text/plain` for empty files, to
ensure they would open in a text editor. But `text/plain` is not really
correct for an empty file: the content isn’t text because there is no
content. The file could eventually become something else when written
to.
Text editors which want to be opened for new, empty files should add
`application/x-zerosize` to their list of supported content types.
Users who want to set a handler for `application/x-zerosize` on their
desktop should use
```sh
gio mime application/x-zerosize # to see the current handler
gio mime application/x-zerosize org.gnome.gedit.desktop # to set it
```

These are here to prevent linker errors, since `gcontenttype.[ch]`
aren’t compiled on Windows or macOS.
The implementations are stubs to be filled out by someone who knows each
platform, at some point in the future.

Those files got renamed to .c to work around an automake issue, but
Meson needs them to have .m extension. Better rename them at build time
in Makefile.am since that's where the workaround is needed.
