complex zeros on systems where the log1p function fails to respect
the sign of zero.  This fixes a test failure on AIX.

doesn't preserve the zero sign (if TANH_PRESERVES_ZERO_SIGN define is 0).

  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 :)
