I am experimenting with putting visibility-default attributes on all struct/classes in libc++.  This checkin decorates only basic_string and vector as an experiment, and for review by those in this audience that might know more about visibilty than I do.  If I get no negative feedback on this procedure I will begin to decorate the entire library in this way.

Changed __config to react to all of clang's currently documented has_feature flags, and renamed _LIBCPP_MOVE to _LIBCPP_HAS_NO_RVALUE_REFERENCES to be more consistent with the rest of the libc++'s flags, and with clang's nomenclature.

patch by Jeffrey Yasskin for porting to Ubuntu Hardy.  Everything was accepted except there were some bug fixes needed in <locale> for the __nolocale_* series.  For the apple branch I ended up using templates instead of the var_args solution because it seemed both safer and more efficient.
