da574a47d0 Handle in-vector with range arguments. 
* Add `normalise-inputs` to special function env.
* Treat eta-expansion specially. Now
    `(lambda (x ...) (f x ...))`
  will typecheck like `f` but with a type restricted to
  the size of `x ...`.

  Currently, this special case only works for non-polymorphic
  functions.

5d4477d08d safe & efficient (-> Any Boolean) contract 
New strategy for compiling the (-> Any Boolean) type to a contract.
When possible, uses `struct-predicate-procedure?` instead of
 wrapping in `(-> any-wrap/c boolean?)`.
Makes exceptions for untyped chaperones/impersonators over struct predicates;
 those are always wrapped with `(-> any-wrap/c boolean?)`.

This change also affects (require/typed ... [#:struct ...]), but not #:opaque

5fa40de546 Avoid ignoring class/unit forms at the top-level 
Possibly a better long-term solution (for after the release)
is to not use the ignore property here and instead just use the
ignore table.

b5dc5585be Fix part of GH issue #208 
For private `define-values` in classes with multiple variables, don't
eagerly throw type errors in the synthesis step. Instead, wait
until the later checking step when the environment will be correctly
set up.

When the initial synthesis typecheck fails, yield type Any for
the environment. If the typecheck should really fail, this is ok. If
not, then the user can add a type annotation.

A better long-term strategy is to change the handling of environments
so that the type environment gets refined as definitions are checked.
This way all annotations that the user writes are factored into the
initial environment and unannotated variables will have their types
synthesized.

3d91ebeb4c Increase timeout instead of removing it.

The random tester has its own timeout, which doesn't cause drdr to error.
