Issues #3167 , #3682 : tests for math.log and math.log10 were failing on

Solaris and OpenBSD. Fix this by handling special values and domain
errors directly in mathmodule.c, passing only positive nonspecial floats
to the system log/log10.

trailing whitespace, and reformat to fit into 80
columns.

OverflowError incorrectly on this platform, presumably as a result of
the libm setting errno = ERANGE for this call.

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 :)
