  Completely changed the way the XPath evaluation is done, likely to break
  stuff like libxslt right now:
  - Makefile.am: detect XPath memleaks in regreson tests
  - error.c: fixed and error w.r.t. error reporting still using
    stderr
  - hash.c: added new line at end of file
  - tree.h: minor cleanup
  - xpath.[ch] xpointer.[ch]: Major changes ! Separated XPath
    expression parsing from evaluation, resulted in a number of
    changes internally, and in XPointer. Likely to break stuff
    using xpathInternals.h but should remain binary compatible,
    new interfaces will be added.
