8c1dbae88b expander: improve extractor to recognize once-set variables 
When `set!` is used to tie a recursove knot in a flattened linklet,
the expander can recognize that pattern and not complain that a
mutable variable might be shared across places. Improving that
inference means fewer `++global-ok` flags in Makefiles.

This commit also avoids single-quote as an escaping form in a
makefile, which doesn't work with nmake on Windows.

f00de510de cs configure: support installed libz and libzl4 
Continue to build the bundled-with-Chez zlib and lz4 by default, but
support `--enable-libz` and `--enable-liblz4`, and turn those on when
the Chez Scheme directory doesn't have bundled versions. That should
make things build right for distributions where repackaging
dependencies is disallowed or discouraged.

90b79524aa revise build to avoid ld and nicear 
The Chez Scheme build process now create an archive instead of linking
"kernel.o". Adjust the Racket CS build to use archives instead of
"kernel.o".

Also, modernize the Racket build's use of `ar`. Using the flags `rc` by
default (instead of `ruv`) should avoid the need for `nicear`.

db3b75eaf1 expander: add shadow filesystem for Windows in collection lookup 
Checking for directories when searching for a collection can be
especially slow with the Windows filesystem, but Windows also supports
filesystem-change events. So, cache information about the existence of
paths, relying on filesystem-change events to detect with the cache is
out of date.

Related to racket/drracket#281

35ff9137e7 cs: tweak return for call/ec and call-with-continuation-barrier 
The prompt installed for an escape continuation or continuation
barrier is never used to delimit a captured continuation, so the
return from the continuatiton can be streamlined slightly.

The benefit is very small (but detectable in the macro expander's use
of barriers). There's an opportunity to use `call/1cc` instead of
`call/cc`, but that change does seem to help --- neither Chez Scheme's
current `call/1cc` nor the opportunistic variant of `call/cc` use to
implement continuation attachments.
