	* include/bits/stl_list.h:
	* include/bits/list.tc:
	* src/list.cc:
        Performance enhancements for destructor, push_front(),
        push_back(), pop_front(), pop_back(), sort()
        Eliminated static_casts where possible.
        Moved code out of header files into new src/list.cc
        implementation file for library where possible.
        Remove inheritance from iterator class and create separate
        classes for non-constant and constant iterators.
	* include/bits/stl_tree.h (_Rb_tree class):
	* src/tree.cc:
        Only erase contents in destructor.
        Eliminate unnecessary initialization in assignment operator.
        Optimize for the nominal case by not checking whether
        container is empty in clear().
        Re-order test in _M_insert() to improve performance.
        Move initialization of new node's left & right pointers to
        src/tree.cc to where new node's colour is initialized
        and to reduce the amount of inline code.
        Use  _M_leftmost() and _M_end() to improve readability where
        appropriate.
        Create separate classes for non-constant and constant
        iterators to clarify code, avoid extra template parameters and
        casting away constness.
