fce98517e6 Fix rest arg contract generation for case-> types 
The generated contracts are still not ideal when more than
one case has a rest argument, since a later case in the
case-> contract may pass but case-> won't try all of them.

a7ad0e3a01 default module name resolver: fix cache 
The cache was keyed on `current-library-collection-paths`, but
not other parameters such as `current-library-collection-links`,
so it was too "sticky" in the case that some parameters changed.
Adjust the cache to be specific to loaded module in a namespace's
module registry.

9435a8f447 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.

5ed9b65ae5 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.

c64d70abc6 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?'

98b91a11e4 faster path for TCP input 
Avoid polling a file descriptor to determine whether it has bytes;
just try to read, and then go to epoll/kevent mode when available,
skipping a poll/select.

97da48ab67 remove/adjust obsolete C preprocessor cases 
Mac OS Classic and Palm ae long since unsupported.

TCP support implies sockets (since old Mac TCP is gone).

For what it's worth, make the build work without TCP support, although
no one ever builds that way.

58e8ed7d7d games/cards: add @2x card images 
For both original and @2x, adjust images to use alphas for the corner,
instead of drawing with clipping, which avoids alignment problems on
an @2x display.

54e42664df racket/draw: faster (on some platforms) path for drawing a bitmap 
The faster path applies in the common case of drawing a whole
bitmap, as opposed to a section of the bitmap.
