backward PP compatability. Add BOOST_category_item_AVAILABLE as a defined, or not, symbol for use with "#ifdef" or "#ifndef". Add documentation of macros used for detection and version information. Also replace direct use of BVN(0,0,0) and BVN(0,0,1) with more meaningful macros that are globally defined, and hence consistent.
