32a79a22ec Revert "improve the way plus-one arity functions fall back when they can't see the application site" 
This reverts commit c24ddb4a7c.

This optimization was bogus, as shown by the test case in 393d72f153

(Thanks to Sam again for the test case.)

3e53a3ea42 make impersonator vector contracts use impersonate-vector, not chaperone-vector 
closes #1198

c24ddb4a7c improve the way plus-one arity functions fall back when they can't see the application site 
In particular, instead of going directly back to the chaperone, handle
the case where the function doesn't accept keyword arguments with a
less expensive fallback.

The less expensive fallback uses a case-lambda wrapper (wrapped inside
a make-keyword-procedure) to close over the neg-party and avoid the
chaperone creation. With this commit, the program below gets about 3x
faster, and is only about 20% slower than the version that replaces
the "(let ([f f]) ...)" with its body

  #lang racket/base
  (module m racket/base
    (require racket/contract/base)
    (provide (contract-out [f (-> integer? integer?)]))
    (define (f x) x))
  (require 'm)
  (collect-garbage)
  (time (for ([x (in-range 5000000)]) (let ([f f]) (f 1))))

  Thanks, @samth!

273bc4ea49 use OS X native SSL when libssl is too old 
OS X's libssl is deprecated, and it doesn't work with SSL connections
that need SNI. We'll distribute out own libssl builds for OS X via a
package, but we need a native implementation that works well enough to
get that package.

92f1bfa4d2 openssl: add 'secure protocol shortcut 
The 'secure protocol symbol is just a shorthand for
`(ssl-secure-client-context)`, but it helps highlight
that the default 'auto isn't secure, and having a plain
symbol smooths the connection to native Win32 and OS X
implementations of SSL.

1e5da68b88 OS X: avoid getdtablesize() by switching frmo select() to poll() 
The getdtablesize() result appears not to be constant on OS X.
Creating some combination of CFStream objects, threads, and CFRunLoop
objects can cause the value to be increased by a factor of 10. Avoid
the need for getdtablesize() by switching from select() to poll().

3df12dca58 specialize sequence/c for one-element sequences 
this yields only a modest speed up and only when iterating
over long sequences, e.g. like in this program:

  #lang racket/base
  (require racket/sequence racket/contract/base)
  (define s (make-string 10000 #\a))
  (define str (contract (any/c . -> .  (sequence/c char?))
                        (λ (x) (in-string s))
                        'pos 'neg))
  (time
   (for ([x (in-range 100)])
     (for ([x (str 0)])
       (void))))
