    libdocument: Add transfer annotation for ev_document_get_info
    
    The GIR annotation currently defaults to transfer-ownership="full",
    which results in a double-free when using this function through GIR.
    Change this to "transfer none" to let GIR know that it should not free
    the returned EvDocumentInfo.
    
    Closes #1125
