  Fix and add const qualifiers
  
  For https://bugzilla.gnome.org/show_bug.cgi?id=689483
  
  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
