6cafda8916 Decouple syntax-case from the Chibi core. 
This restores third-party (ab)users of the Chibi macro system such
as in https://gist.github.com/baguette/2632464, while allowing us
to break those uses in more interesting ways.

It also keeps the core slightly smaller (both in C and Scheme)
and speeds up the macro expansion process.

439e35da61 Check for valid "rest" parameters in parameter lists 
Checks for invalid parameter names and duplicate parameters were
being performed on parameter lists, but these checks were not
considering any rest parameters.  This means that

  ((lambda (x . x) x) 'foo 'bar)   =>  foo
  ((lambda (x . 0) x) 'foo 'bar)   =>  foo
  ((lambda (x . #t) x) 'foo 'bar)  =>  foo
  ((lambda 0 'foo))                =>  foo
  ((lambda #t 'foo))               =>  foo

and so on.  Now these all produce errors.

b25e46b11b Introduced a second version of sexp_double_to_ratio, named 
sexp_double_to_ratio_2, which converts without introducing
round-off errors the way sexp_double_to_ratio does when it
multiplies by 10.

Changed sexp_inexact_to_exact to use this new function when
a non-zero fractional part of the input exists.

e092923aac Win32: Fix win32 port 
Try to fix win32 port. Now it runs both on Win32/Win64.

Win64 port currently depends on 128bits arithmetic thus it does not run on
MSVC.

Makefile now have EXCLUDE_POSIX_LIBS knob to exclude posix related library
from build.

Introduce msys PLATFORM for Makefile.detect to use MSYS's POSIX
emulation layer. It is intended for linking against MSYS tools; it is
not for embedding to Win32 applications.
