[PATCH] Char: cyclades, cleanup

Browse source 
- remove cvs rcsid and alter code that uses it.
- allow a semicolon after use of macro to not confuse parsers (e.g. indent)
  by do {} while (0)
- JIFFIES_DIFF is simple subtraction, subtract directly
- returns cleanup -- do not put values in parenthesis and do not return nothing
  at the end of void functions
- comments are /* */ in C (not //)
