 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.
