050c1022c9 Replace abstract-results with replace-names. 
Also moves large comment over to with replace names since it is now
doing the heavy lifting.

76c3ec443f Remove ability to check unreachable code. 
If code is unreachable then looking up any variable should return
Bottom. But implementing checking unreachable code that way is not that
useful.

49691c4000 fix glib build for Windows 64 
The previous build attempted to cooperate with Valgrind in a way that
truncates a 64-bit address to a 32-bit address. Disable Valgrind
cooperation. (Other builds seem ok for now, but future rebuilds will
disable Valgrind cooperation for them, too.)

aa487175ad change default MSVC projects to Visual Studio 2010 (version 10) and up 
Visual Studio 2008 is still supported by "9.sln" projects and
".vcproj" files, while ".sln" and ".vcxproj" work for 2010, 2012,
and 2013. The "build.bat" script detects which version of
Visual Studio is active and uses the appropriate ".sln" files.

The bad news is that we have two copies of each project until we
decide to drop support for Visual Studio 2008. (We had two copies
before, but one copy was unmaintained.) The good news is that
we have only 2 copies of each project, because recent versions of
Visual Studio are willing to use 2010 projects as-is.

Change project and related files to text instead of always CRLF,
because that seems to be ok for modern Windows tools.

b7610c405d distro-build: move a file out that is accessed directly 
The "pack-all.rkt" file is needed before (and only before) the
distro-build package itself is ready, so move it to the "racket/src"
directory.

17451d9662 Revert "change recursive-contract to reject cyclic values" 
This reverts commit d664ee1430.

This commit broke recursive-contract because it disallowed any sharing,
not just cycles. And fixing this in the obvious way leads to about a 20x
slowdown (compared to v6.0's recursive-contract) on the micro-benchmark
mentioned in the original change to recursive contract.

So, for now, just go back to accepting cycles.

d664ee1430 change recursive-contract to reject cyclic values 
For a few reasons:

 - this seems to fit better with how TR already works

 - cyclic values are something that, at least in my experience,
   abstractions are not generally equipped to handle (and,
   perhaps worse, don't seem all that useful when weighed against
   the non-termination problems that can come up)

 - there was a suspicious case in the projection where, when a
   cycle was detected the projection just returned its argument
   (the place in the diff for this commit where there is now a
   call to raise-blame-error). I couldn't get this to cause problems,
   but this might just be because I'm not smart enough

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)))
