This handles contract generation for recursive or
mutually recursive Name types in the static contract
framework.
Instead of just generating recursive-sc static contracts,
it memoizes the recursive contract within a single
type->contract call by indirecting through a table.
When static contracts are instantiated, the table is
consulted for computing contract kind information and for
generating the actual contracts for the recursive names.

This bug manifested in having extraneous class
members in a type for a class whose superclass
expression was a mixin application.

The type alias analysis is unable to detect a rare kind
of type dependency and as a result initializes type aliases
in an order that doesn't work. Adding the extra `Class`
boilerplate here accommodates the analysis.
Please merge to v6.1.1

Mandatory kw arguments in function types could confuse
the typechecker when the function had the
`syntax-procedure-converted-arguments-property` property
set.

The thing that caught my eye is the missing `#:cache-keys?' which should
really be there. But not too important.

Sounds like a bad name, but I don't have anything better. It's not some
"current-...-print" thing since it works on the sexpr that is intended
to be pretty-printed. So I went with the above.

Asumu said that he doesn't know of any other clients of this parameter
besides my class code.

This uses a technique discovered by Ryan and Dan that
allows the typed class macro to function without invasively
local-expanding the entire class macro (using its private
context information).
Instead, it expands into many helper macros inside the
normal class body and communicates among them using
`syntax-local-value` and compile-time state within the
class body.
This rewrite didn't save that many lines, but it did
reduce the amount of magic that's used.

The types are tweaked to match the contracts and to support passing a
list of headers to the connect procedure.
The FIXME for polymorphism has also been removed as it is now
parameterized to support "...The result of the handle procedure is the
result of call/input-url..."

Subtyping on objects was unsound due to an attempt to
make the algorithm more clever. This was a good lesson in
the danger of premature optimization.

My fix had just patched over a contract violation in a different
function. This commit fixes the root of the problem.
