Log message:
          - Function vfscanf() is rewriten. The float point version is optimized
            considerably: the expense of a stack was cut by half, and the size 
of
            function has decreased approximately on 1KB. Opportunities of 
standard
            and minimal versions are expanded, and their size has remained at a
            former level.
        
            Briefly:
              . Restrictions of a float point format are eliminated.
              . Conversion '%[' is present in standart version now.
              . The minimal version differs from standard only absence of '%[' 
conv.
              . The 'hh' type qualifier is added ('char *', C99).
              . The maximal field width is increased up to 255 (65535 in float 
version).
              . All known bugs are fixed.
        
            New vfscanf() concedes old in:
              . The size of the minimal and standard versions has increased for 
old
              branches of compiler (less 4.1) and ancient chips (without MOVW).
              . The maximum quantity of conversions now is limited (255).
