    g_steal_pointer: make it C++ clean
    
    We have a test that #includes our headers from a C++ program to make
    sure we don't throw any errors or warnings as a result of that.
    
    The new inline implementation of g_steal_pointer() does an implicit
    conversion from (void *), which is not valid in C++.
    
    Add a cast to avoid the problem.
    
    Thanks to Ignacio Casal Quinteiro for the report.
