    extension: Mark entry points as not introspectable
    
    As pointed out by Emmanuele Bassi, these are not part of the ABI and
    should be marked with (skip).
    
    See: https://discourse.gnome.org/t/vala-bindings-for-an-unusual-c-ownership-function-signature/8184
    
    
    (cherry picked from commit 4309509d51767bed06a4a74f07d846d11a3912a8)
