Change float_t and double_t to long double on i386. All floating point expressions on i386 are evaluated in the range of the long double type, so this is wrong in a different but hopefully less worse way than before. Since expressions are evaluated in long double registers, there is no runtime cost to using long double instead of double to declare intermediate values (except in cases where this avoids compiler bugs), and by careful use of float_t or double_t it is possible to avoid some of the compiler bugs in this area, provided these types are declared as long double.
I was going to change float.h to be less broken and more usable in combination with the change here (in particular, it is more necessary to know the effective number of bits in a double_t when double_t != double, since DBL_MANT_DIG no longer logically gives this, and LDBL_MANT_DIG doesn't give it either with FreeBSD-i386's default rounding precision. However, this was too hard for now. In particular, LDBL_MANT_DIG is used a lot in libm, so it cannot be changed. One thing that is completely broken now is LDBL_MAX. This may have sort of worked when it was changed from DBL_MAX in 2002 (adding 0 to it at runtime gave +Inf, but you could at least compare with it), but starting with gcc-3.3.1 in 2003, it is always +Inf due to evaluating it at compile time in the default rounding precision.

Implement fpclassify(): o Add a MD header private to libc called _fpmath.h; this header contains bitfield layouts of MD floating-point types. o Add a MI header private to libc called fpmath.h; this header contains bitfield layouts of MI floating-point types. o Add private libc variables to lib/libc/$arch/gen/infinity.c for storing NaN values. o Add __double_t and __float_t to <machine/_types.h>, and provide double_t and float_t typedefs in <math.h>. o Add some C99 manifest constants (FP_ILOGB0, FP_ILOGBNAN, HUGE_VALF, HUGE_VALL, INFINITY, NAN, and return values for fpclassify()) to <math.h> and others (FLT_EVAL_METHOD, DECIMAL_DIG) to <float.h> via <machine/float.h>. o Add C99 macro fpclassify() which calls __fpclassify{d,f,l}() based on the size of its argument. __fpclassifyl() is never called on alpha because (sizeof(long double) == sizeof(double)), which is good since __fpclassifyl() can't deal with such a small `long double'.

Use the correct values for LDBL_*. Libc doesn't completely support long doubles at the moment (printf truncates them to doubles). However, long doubles to appear to work to the ranges listed in this commit on both -stable (4.5) and -current. There may be some slight rounding issues with long doubles, but that's an orthogonal issue to these constants.
I've had this in my local tree for 3 months, and in my company's local tree for 15 months with no ill effects.

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.
