2847d1d22a improve atan, asin, and acos on complex numbers

Complex Elementary Functions" as implemented in Chez Scheme.

5f92ffa3c4 improve asin acos on +inf.0 and -inf.0 
Avoid tripping into +nan.0 by using 0 instead of 0.0
for the imaginary part of a real number and by using
`atan` with two arguments instead of one.

d31368fc09 improve expt on exact non-integer second argument 
Correct the case that converting the second argument to an inexact
numbe produces an integer by losing precision.

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.

9f1fe73797 change build to use archives instead of merging objects 
Merging ".o" files to one "kernel.o" can be convenient for further
linking, but it requires running `ld` directly. Running `ld` directly
sometimes runs into a mismatch between the C compiler and the default
`ld`. It's better to use the more typical approach of collecting
objects into an archive.

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`.
