Summary:                    adding math functions as of current svn
Description: 
exp2 is too big, so I have left it out for now (the glibc implementation
uses
functions not in uclibc, newlib does not have it)
nexttoward is present as alias to nextafter in glibc, not done
all the rest listed in float_wrappers is done

consider dropping the comment/support for rem_pio2f, it was used by the
Sun
implementations of sinf/cosf/tanf, but due to latest changes in svn,
these
are implemented from their double counterparts
the susv3 patch removes the ceilf and floorf implementations, using
floatwrapper instead

----------------------------------------------------------------------

----------------------------------------------------------------------
the ldouble patch adds long double versions (similar to float_wrapper)
corrects the fact, that llrint and llround were not built and corrects
the
comment in the float_wrapper, exp2,nearbyint,nexttoward add the last
missing
functions as of SuSv3
nexttoward() is an alias to nextafter in glibc, but they are different
implemented as wrapper

----------------------------------------------------------------------

----------------------------------------------------------------------
the math_priv patch adds __ieee754_log2 to the list, and removes all those
that
are not used. with this patch libm builds cleanly.

----------------------------------------------------------------------

----------------------------------------------------------------------
fpmacros and ldouble-option (apply in this order) add
UCLIBC_HAS_LONG_DOUBLE_MATH
option, and changes all the references of __NO_LONG_DOUBLE_MATH to this.
As of the current configs, only i386/m68k/sparc64/x86_64 are the archs
that
have long double, so the option is limited to these
I have also added/enabled
__fpclassifyl,__finitel,__singbitl,__isinfl,__isnanl
