closes PR 14798 (the previous commit, 86017992ab, that
claimed to fix this PR is unrelated; sorry for that)
Please include in 6.1.1

There seems to be a problem in kqueue() on Mac OS X for watching for
FIFO write availability, where adding a read event for the same FIFO
(at a different file descritor) can disable the write event.

The thing that caught my eye is the missing `#:cache-keys?' which should
really be there. But not too important.

Sounds like a bad name, but I don't have anything better. It's not some
"current-...-print" thing since it works on the sexpr that is intended
to be pretty-printed. So I went with the above.

In particular, a #f argument can make sense if the length is 0.
Technically, a byte string's byte array is supposed to be nul-terminated,
but many uses of byte strings get away without that terminator. I've
adjust the documentation to note that `bytes-copy` will work with a
non-terminated byte string.

This bug could result in weird "cannot re-define a constant: lifted.0.2"
errors, or probably even worse collsisions of definitions, but I think
only in a namespace created from `module->namespace`.
So far, I haven't been able to create a reasonably small test,
because so many things have to line up in just the right way.

Based on the core file, this bug seems likely responsible for the
`raco setup` crash on DrDr for push 29346.

The `--enable-natipkg` configuration option adds "-natipkg" to the
platform library subpath. The suffix is intended to trigger the
installation of packages that supply native libraries for supported
platforms (where 64-bit Linux is the supported platform, for now, for
main-distribution packages), instead of relying on libraries installed
via the OS's package manager.
The intended client for "-natipkg" is the package-build service, where
installing packages via the OS package manager would require network
access and either trust or constrained installations. The build
machine is intentionally disconnected from the network and can only
access Racket packages, so repackaging native libraries as Racket
packages makes those libraries accessible.
A disadvantage of this approach to installing native libraries is that
it creates work for implementers of packages that access native
libraries. Those implementers will have to supply packages for 64-bit
Linux versions of native libraries to the degree needed to build and
(eventually) test the package. An advantage of the approach is that it
requires no changes to the package system; it will be cheap to replace
this approach if we find a better way to deal with native libraries
and/or OS packages in the package-build service.
