Fix some regressions caused by the switch from gcc to clang. The fixes are workarounds for various symptoms of the problem described in clang bugs 3929, 8100, 8241, 10409, and 12958.
The regression tests did their job: they failed, someone brought it up on the mailing lists, and then the issue got ignored for 6 months. Oops. There may still be some regressions for functions we don't have test coverage for yet.

Various changes to improve the accuracy and speed of log{2,10}{,f}. - Rename __kernel_log() to k_log1p(). - Move some of the work that was previously done in the kernel log into the callers. This enables further refactoring to improve accuracy or speed, although I don't recall the details. - Use extra precision when adding the final scaling term, which improves accuracy. - Describe and work around compiler problems that break some of the multiprecision calculations.
A fix for a small bug is also included: - Add a special case for log*(1). This is needed to ensure that log*(1) == +0 instead of -0, even when the rounding mode is FE_DOWNWARD.

Another minor nit: Make sure the constant here is a float so the compiler doesn't promote the entire expression to double.

Fix formatting, this is hard to explain, so I'll show one example.
- float ynf(int n, float x) /* wrapper ynf */ +float +ynf(int n, float x) /* wrapper ynf */
This is because the __STDC__ stuff was indented.

Assume __STDC__, remove non-__STDC__ code.

Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

Second part of update to fdlibm 5.2: speed up argument reduction for trig functions in the case pi/4 < |x| < 3pi/4.
Remove unused static constants ("one").

J.T. Conklin's latest version of the Sun math library.
-- Begin comments from J.T. Conklin: The most significant improvement is the addition of "float" versions of the math functions that take float arguments, return floats, and do all operations in floating point. This doesn't help (performance) much on the i386, but they are still nice to have.
The float versions were orginally done by Cygnus' Ian Taylor when fdlibm was integrated into the libm we support for embedded systems. I gave Ian a copy of my libm as a starting point since I had already fixed a lot of bugs & problems in Sun's original code. After he was done, I cleaned it up a bit and integrated the changes back into my libm. -- End comments
