parsers: statically initializing tp_new to PyType_GenericNew is not portable

As detailed on http://docs.python.org/extending/newtypes.html (quote):

  "In this case, we can just use the default implementation provided by the API
  function PyType_GenericNew(). We’d like to just assign this to the
  tp_new slot, but we can’t, for portability sake. On some platforms or
  compilers, we can’t statically initialize a structure member with a function
  defined in another C module, so, instead, we’ll assign the tp_new slot in the
  module initialization function just before calling PyType_Ready()."

Fixes "gcc (GCC) 3.4.5 (mingw-vista special r3)" complaining with:

  mercurial/parsers.c:1096: error: initializer element is not constant
  mercurial/parsers.c:1096: error: (near initialization for `indexType.tp_new')
