Mark Dickinson b08a53a99d Issue #1580: use short float repr where possible.
- incorporate and adapt David Gay's dtoa and strtod
   into the Python core
 - on platforms where we can use Gay's code (almost
   all!), repr(float) is based on the shortest
   sequence of decimal digits that rounds correctly.
 - add sys.float_repr_style attribute to indicate
   whether we're using Gay's code or not
 - add autoconf magic to detect and enable SSE2
   instructions on x86/gcc
 - slight change to repr and str:  repr switches
   to exponential notation at 1e16 instead of
   1e17, str switches at 1e11 instead of 1e12

  Issue #4575: fix Py_IS_INFINITY macro to work correctly on x87 FPUs.

  Oops.  Need to check not only that HAVE_DECL_ISINF is defined, but also
  that it's equal to 1.  (If isinf isn't defined, HAVE_DECL_ISINF is
  defined to be 0, rather than being undefined.)

  Add autoconf test to detect x87-style double rounding, as described in
  issue #2937.  This information can be helpful for diagnosing platform-
  specific problems in math and cmath.  The result of the test also
  serves as a fairly reliable indicator of whether the x87 floating-point
  instructions (as opposed to SSE2) are in use on Intel x86/x86_64 systems.

  isinf and isnan are macros, not functions; fix configure script

  I finally got the time to update and merge Mark's and my trunk-math branch. The patch is collaborated work of Mark Dickinson and me. It was mostly done a few months ago. The patch fixes a lot of loose ends and edge cases related to operations with NaN, INF, very small values and complex math.

  The patch also adds acosh, asinh, atanh, log1p and copysign to all platforms. Finally it fixes differences between platforms like different results or exceptions for edge cases. Have fun :)
