[librsvg: 5/32] Add LoadingError::OutOfMemory

[Federico Mena Quintero <federico src gnome org>]

commit 975ce85a0ad5a64c234ea57be526c457cd76fe8a

    Add LoadingError::OutOfMemory
    
    The code doesn't't catch OOM yet during loading in general, for example, while
    creating Node structures.  In the future I'd like to do this, so I'll
    leave this error code in place.
