* 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.
