Simplify use of FOR_EACH_TAIL
* src/data.c (circular_list): New function.
* src/lisp.h (FOR_EACH_TAIL): Use Brent’s algorithm and C99 for-loop
decl, to eliminate the need for the args TAIL, TORTOISE and N, and
to speed things up a bit on typical hosts with optimization.
All uses changed (Bug#25605).
