18662741fb Fix signature-checking bug with DMdA's `define-record-procedures'. 
Define the predicate before the constructor, as the predicate may be
used in checking the signature of the constructor.

eebe5b2e2b 2nd attempt at generators for records/structs. 
This time, with feeling.

f706b0d7a7 Revert "Create arbitraties off parametric struct/record signature constructors." 
This reverts commit 7df9a22a67.

It was broken in several ways.  New attempt later.

2c964b91f0 Provide prop:print-converter propery with `define-record-procedures'. 
This fixes quasiquote and constructor-style printing to not fall for
the extra lazy-contract-checking field.

93d7ec9446 Don't recheck DMdA lazy contracts we've already checked. 
We avoided re-applying contracts that haven't been checked, but not
those that have.  Do so now.

5f8924b1d2 Fix various interaction breakage between the new DMdA records and the stepper. 
Namely, attach the `stepper-ignore-completely' property to each
individual definition, rather than just to the block of definitions as a whole.

b4f010c6d5 Fix breakage due to lazy contracts. 
- fix check for lazy-wrap property
- supply hash procedures for records defined with `define-record-type'
  (needed by the stepper)

698199d68c Massage syntax of `define-record-procedures-parametric'. 
Now 

(define-record-procedures-parametric pare pare-of
  make-pare pare?
  (pare-one pare-two))

instead of the old

(define-record-procedures-parametric (pare a b)
  make-pare pare?
  (pare-one pare-two))
