This change excludes boost:: and boost::detail:: namespaces from ADL for unqualified function calls (e.g. algorithms). This reduces the possibility of name clashes with other libraries and user's code. One of the effects should be fixing test failures on gcc 4.2 and 4.4 due to clashed with Boost.TypeTraits.
Also some of the functions marked with inline keyword.

changes.
for handling vc6/7 deficiencies with iterator_traits.
Fixed a bug in iterator_facade which was causing incomplete types to
be passed through is_convertible.
Reinstated libs/utility/iterator_traits_test.cpp
