c9d4e0fb8c win32: fix `copy-file' handling of file-exists error 
The specific error reported by CopyFileW doesn't seem
to be documented. It's unclear whether Racket's old test
for ERROR_EXISTS_ALREADY was the wrong choice (as opposed
to ERROR_FILE_EXISTS) or whether some Windows versions
use it; we test for both for now.

Also, improve error reporting when an errno or
GetLastError() value is available.

3ba93cb165 Add a heuristic for case-lambda type simplification. 
Makes simplification _much_ faster for types that have a single most
general case. That includes most numeric functions.

01396784c9 Fix set/c to conform to hash/c-like restrictions. 
Since sets are implemented using the elements as the domain of a hash table,
the following must be true:
 * element contracts for (seteq ...) must be flat
 * element contracts for (seteqv ...) must be flat
 * element contracts for (set ...) must be chaperones, and the resulting
   contract is a chaperone contract

Also, change higher-order set/c contracts to be chaperone contracts
due to the new restrictions.

70e1d63bed Add a function to print whole types. 
With this, it's possible to get more information than the simplified
types shown at the REPL. The types are as unwieldy as ever, but you
have to ask for them explicitly.

This is not an adequate long-term solution, and will be replaced by a
"Type Explorer" tool.
