gio-sys::g_memory_input_stream_new_from_data should take a *const u8

[withoutboats]

According to the docs, this function takes a const pointer, whereas the Rust bindings take a *mut u8.

Thanks for reporting, I'll keep this in mind when iterating on the sys crate generator.

I think this same issue affects gtk-sys::gtk_drag_dest_set where the targets argument should be a *const GtkTargetEntry.
