Define LDBL_NBIT to be a mask indicating the position of the integer bit in a long double. For architectures that don't have such a bit, LDBL_NBIT is 0. This makes it possible to say `mantissa & ~LDBL_NBIT' in places that previously used an #ifdef to select the right expression. The optimizer should dispense with the extra arithmetic when LDBL_NBIT is 0.

Fix printing of long doubles to match the size that gcc is using. This fixes devstat consumers (like vmstat, iostat, systat) so they don't print crazy zillion digit numbers for disk transfers and bandwidth.
According to gcc, long doubles are 64-bits, rather than 128 bits like the SVR4 ABI spec wants them to be.. Note that MacOSX also treats long doubles as 64-bits, and not 128 bits, so we are in good company.

Add __ldtoa(), a wrapper around gdtoa() to make it look like dtoa(). In support of this, add some MD macros to assist in converting long doubles to the format expected by gdtoa().

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'.
