  Fix malloc debug macros to work properly with h323.
  
  The main problem here was that cstdlib was undefining free thereby causing the
  proper debug macros to not be used. ast_h323.cxx has been changed to call
  ast_free instead to avoid the issue. Because using the ast prefix calls are
  a better choice, ast_free_ptr is the new wrapper for free to pass to functions.
  Also, a little bit of clean up was done to avoid the debug macros intentionally
  being redefined.
