Mike Barcroft 8cf5ed5125 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'.

This was developed by David Schultz and myself with input from bde and
fenner.

# All library objects contain FreeBSD revision strings by default; they may be
# excluded as a space-saving measure. To produce a library that does
# not contain these strings, add -DSTRIP_FBSDID (see <sys/cdefs.h>) to CFLAGS
# below. Note, there are no IDs for syscall stubs whose sources are generated.
# To included legacy CSRG sccsid strings, add -DLIBC_SCCS and -DSYSLIBC_SCCS
# (for system call stubs) to CFLAGS below. -DSYSLIBC_SCCS affects just the
# system call stubs.
