Fix type printing for simple latent filters
...
Don't print a simple filter for a function with more than
one argument or with a filter object that refers to an outer
variable.
This matches up with type parsing.

add a random generator for struct/c
...
This is actually done by adding a generator for struct/dc in the case
that there are no dependencies, so it'll also work for such contracts.

contract improvements
...
- add a generator for cons/c
- make flat-rec-contract not just build the predicate, meaning:
- it has a better name
- it can do random generation
- make the procedures that come from any/c random generation indicate that from their names
- make or/c with one argument just (check and) return that argument, so
(or/c (or/c number?)) has the name 'number?'

fix a performance bug in drracket's REPL IO.

This one of those classic n^2-loop-that-should-be-linear bug. The fix
speeds up this program (when run in DrRacket) by about 1.75x:
(for ([x (in-range 10000)])
(display "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz\n"))
The bug is fairly old too: I introduced this bug on March 6th,
2004. (Thanks, Sam, for making that old history accessible!)
