David Schultz 240dbabfa8 Implement the classification macros isfinite(), isinf(), isnan(), and 
isnormal() the hard way, rather than relying on fpclassify().  This is
a lose in the sense that we need a total of 12 functions, but it is
necessary for binary compatibility because we have never bumped libm's
major version number.  In particular, isinf(), isnan(), and isnanf()
were BSD libc functions before they were C99 macros, so we can't
reimplement them in terms of fpclassify() without adding a dependency
on libc.so.5.  I have tried to arrange things so that programs that
could be compiled in FreeBSD 4.X will generate the same external
references when compiled in 5.X.  At the same time, the new macros
should remain C99-compliant.

The isinf() and isnan() functions remain in libc for historical
reasons; however, I have moved the functions that implement the macros
isfinite() and isnormal() to libm where they belong.  Moreover,
half a dozen MD versions of isinf() and isnan() have been replaced
with MI versions that work equally well.

# There are two options in making libm at fdlibm compile time:
# _IEEE_LIBM --- IEEE libm; smaller, and somewhat faster
# _MULTI_LIBM --- Support multi-standard at runtime by
# imposing wrapper functions defined in
# math.h:
# _IEEE_MODE -- IEEE
# _XOPEN_MODE -- X/OPEN
# _POSIX_MODE -- POSIX/ANSI
# _SVID3_MODE -- SVID
#
# Here is how to set up CFLAGS to create the desired libm at
# compile time:
#
# CFLAGS = -D_IEEE_LIBM ... IEEE libm (recommended)
# CFLAGS = -D_SVID3_MODE ... Multi-standard supported
# libm with SVID as the
# default standard
# CFLAGS = -D_XOPEN_MODE ... Multi-standard supported
# libm with XOPEN as the
# default standard
# CFLAGS = -D_POSIX_MODE ... Multi-standard supported
# libm with POSIX as the
# default standard
# CFLAGS = ... Multi-standard supported
# libm with IEEE as the
# default standard
