Add symbol versioning to libxml2 shared libs

* libxml2.syms: the symbols with history, going back to 2.4.30
* Makefile.am configure.in: linking flags detection and use
* parser.c tree.c valid.c xpointer.c: various cleanup of functions
  which could be made static or simply discarded, not that many
