3998	Provide light weight headers for extensibility features of BOOST_FOREACH	Kazutoshi Satoda <k_satoda@…>	Eric Niebler	"To provide specialization as written in [http://www.boost.org/doc/libs/1_42_0/doc/html/foreach/extensibility.html documentation], now users
have to include the whole boost/foreach.hpp which is a somewhat heavy
header, especially when BOOST_FOREACH is actually not used.

This patch extracts the extensibility interface to two new headers:
  - boost/foreach_extensibility_fwd.hpp:
    This includes only forward declations used by the extensibility
    features.
  - boost/foreach_extensibility.hpp:
    This includes also definition of the extensibility features.

Please take care to use ""svn copy"" from boost/foreach.hpp to create
both two new headers to preserve the history.
