    Remove CEIL macro

    This macro was not correct in some cases, and it was used only in
    one place, where we did'nt get any benefit in performance of in size,
    so the macro is removed and ceilf is used instead of it. The only
    function needed from math.h is ceilf, so this patch defines the
    prototype of it instead of including math.h.
