7728e062f4 adjust recursive-contract so that it terminates on cyclic values 
closes PR 14559

This slows down tight recursive contract loops by about 10%, using
the code below as the micro-benchmark:

(require racket/contract/base)

(define c
  (recursive-contract
   (or/c #f (cons/c c c))
   #:flat))

(define n1
  (let loop ([i 500000])
    (cond
      [(zero? i) #f]
      [else (cons (loop (- i 1)) #f)])))

(define n2
  (let loop ([i 500000])
    (cond
      [(zero? i) n1]
      [else (cons (loop (- i 1)) #f)])))

(collect-garbage) (collect-garbage) (collect-garbage)

(void
 (time (contract c n1 'pos 'neg))
 (time (contract c n2 'pos 'neg)))

but we haven't found it yet.

42e0d69746 racket/runtime-path: fix problems with 'so paths 
Search for versions within a library directory, instead of searching
across library directories for a version. That way, user-specific libraries
can take precedence generally.

Fix the construction of library names with versions to match `ffi-lib`.
Specifically, put the version after the suffix on platforms other than
Mac OS X.

Put the code to resolve 'so specs in one place.

5b852cc4bd setup/dirs: adjust get-lib-search-dirs and use if find-dll-dir 
Add `find-dll-dir` to the end, not the beginning, so that it doesn't
override the user's directory. Improve checking for whether the DLL
directory is already covered by the library directories.

e5dd7183b5 file/[un]zip: add UTC and time-rounding option 
A `zip` archive normally holds timestamps in local time; a new option
records/interprets a UTC time instead. (Use the option both to zip and
unzip.) Also, add an option to round the 2-second resolution of time
to the past instead of the future (to avoid files with timestamps in
the future) when zipping.
