Message : 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

 * Summary: Internal Interfaces for memory buffers in libxml2
 * Description: this module describes most of the new xmlBuf buffer
 *              entry points, those are private routines, with a
 *              few exceptions exported in tree.h. This was added
 *              in 2.9.0.
