Preprocessor library updates (Re: [boost] PREPROCESSOR -> PP ?)

I have now committed the change from PREPROCESSOR to PP. The old obsolete
names are retained for now. I also wrote documentation for BOOST_PP_WHILE(),
so it can now officially be used. I also split the unit/regression tests into
multiple files, so that test results can now reveal more information about
preprocessor performance and conformance.

I have also continued R&D of list functionality. The following primitives are
now implemented, but not added to CVS.

    BOOST_PP_LIST_NIL
    BOOST_PP_LIST_CONS(H,T)
    BOOST_PP_LIST_IS_CONS(L)
    BOOST_PP_LIST_IS_NIL(L)
    BOOST_PP_LIST_HEAD(L)
    BOOST_PP_LIST_TAIL(L)

    BOOST_PP_LIST_APPEND(L,R)
    BOOST_PP_LIST_AT(L,I)
    BOOST_PP_LIST_CAT(L)
    BOOST_PP_LIST_FOLD_LEFT(F,R,L)
    BOOST_PP_LIST_FOLD_RIGHT(F,L,R)
    BOOST_PP_LIST_ITER(F,P,L)
    BOOST_PP_LIST_MAP(F,P,L)
    BOOST_PP_LIST_REVERSE(L)
    BOOST_PP_LIST_SIZE(L)

(The names are a mix of Lisp, Ocaml and C++.)

The next thing on my list is to implement arithmetic operations using a list
representation of numbers so that arithmetic performance may be improved.
