Preparation for delivering nicely-formatted error messages in

Boost.Python.  The major change is that, instead of being
boost::function2<PyObject*,PyObject*,PyObject*>, py_function is now a
runtime-polymorphic wrapper for compile-time polymorphic
behavior (just like function) of our own which carries more
information/behaviors.  In particular, you can retrieve an array of
c-strings describing the types in the function signature.
Additionally, the minimum and maximum arity are stored in the
py_function object instead of in the 'function' object which wraps it.

* data_members.hpp -

     Adjustments for the new py_function.  Workarounds for CodeWarrior
     Pro 8.3 bugs in function template argument deduction with
     pointers-to-members.

* has_back_reference.hpp, test/back_reference.cpp,
  test/select_holder.cpp -

     Updated to follow the metafunction protocol

* init.hpp, detail/defaults_gen.hpp -

     Make Keywords a more-specific type in function signatures to
     prevent string literals that show up as char[N] from binding to
     the wrong argument (at least Intel 7.1 for Windows does this).

* make_function.hpp -

     Adjustments for the new py_function.  Arities are now computed
     by caller<>.

* opaque_pointer_converter.hpp, type_id.hpp -

     Use BOOST_NO_EXPLICIT_FUNCTION_TEMPLATE_ARGUMENTS facilities;
     generate specializations that all compilers can handle.

* raw_function.hpp -

     Adjustments for the new py_function.

* caller.hpp -

     Added arity and signature type name reporting.

* detail/config.hpp

     Enable __declspec(dllexport) for Cygwin, thereby fixing the
     recent horrible Cygwin linking problems.


* detail/msvc_typeinfo.hpp -

     Always pass boost::type<T>* explicitly, thereby working around
     incompatible notions of how to specialize function templates with
     default arguments on various compilers.

*   object/function.hpp
  , object/function_handle.hpp
  , object/function_object.hpp
  , object/function_object.cpp

     Adjustments for the new py_function.  Arities are carried by
     py_function.

* object/iterator.hpp, object/iterator.cpp

     Adjustments for the new py_function; we have to compute a
     signature of types to construct it with.

* object/py_function.hpp

     Removed dependency on boost::function; see the comment at the
     top of this entry for more details.

* object/select_holder.hpp

     Clean up to more closely follow MPL idioms.

* test/Jamfile -

     Adjust the embedding test for the new Cygwin use of declspec.
     Update bases and pointee tests with missing properties.

* test/input_iterator.cpp -

     Updates for the new iterator adaptors.

* test/opaque.py -

     Add Python encoding comment to suppress PendinDeprecationWarning
     with recent Python builds.

* test/str.cpp

     Pass a Python long instead of a float to string.expandtabs,
     suppressing a PendinDeprecationWarning with recent Python builds.

* libs/utility/counting_iterator_example.cpp

     Borland workaround

* libs/utility/indirect_iterator_example.cpp

     const-correctness fix.
