0f7d347bd0 Make _LIB_VERSION a weak symbol
That way it can live alongside _LIB_VERSION in libieee.a for
statically compiled programs.

Resolves #14582.

5739f705ee Use integral constants
The compiler is smart enough to convert those into double for powerpc,
but if we put them as doubles, it adds overhead by performing those
operations in floating point mode.

6f2e90e78f Make mantissa type of mp_no configurable
The mantissa of mp_no is intended to take only integral values.  This
is a relatively good choice for powerpc due to its 4 fpus, but not for
other architectures, which suffer due to this choice.  This change
makes the default mantissa a long integer and allows powerpc to
override it.  Additionally, some operations have been optimized for
integer manipulation, resulting in a significant improvement in
performance.

e42a38dd9d BZ#13889: expl (709.75) wrongly overflows for ldbl-128ibm
The patch increase the high value to check if expl overflows. Current
high mark value is not really correct, the algorithm accepts high values.
It also adds a correct wrapper function to check for overflow and underflow.

d22ca8cdfb Make mantissa type configurable

overriding it to take advantage of its FPUs.
