big clean-up patch:

- rename a few functions in var.c to names that make more sense.
- introduce Var_Deletei because it makes more sense.
- rewrite .for loops to use a local LoopVar construct to avoid looking up more
stuff.
- reformat var.c to near K&R
- rewrite most comments in var.c

shown to a few people. millert@ gave me his okay since it passes through
ports correctly.
