    It seems there are functions that do use the const qualifier for some of the
    arguments, but it seems that there are a lot of functions that don't use it and
    probably should.
    
    So I created a patch against 2.9.0 that makes as much as possible const in
    tree.h, and changed other files as needed.
    
    There were a lot of cases like "const xmlNodePtr node".  This doesn't actually
    do anything, there the *pointer* is constant not the object it points to. So I
    changed those to "const xmlNode *node".
    
    I also removed some consts, mostly in the Copy functions, because those
    functions can actually modify the doc or node they copy from
