Locale facets have hidden visibility

Description
When the application or another library is compiled with hidden visibility by default, Boost.DateTime IO facets end up having hidden visibility as well. This breaks libstdc++ locale operations, such as has_facet and use_facet, as these operations are based on dynamic_cast.
Boost.DateTime should work regardless of the default visibility mode the application chooses. All facet types, as well as the types that can be used in their template parameters, should be marked with BOOST_SYMBOL_VISIBLE.
Note:
