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.

Because of the way the C++ standardization process works the

defined version year will not be the commonly known year of the standard.
