fdo#81356: convert Fraction to boost::rational<long> - wip

* Added rational util functions used by Fraction class not
available in the boost::rational class.
* Replaced usage of Fraction by boost::rational<long>
* Removed code that relies on:
1. fraction.IsValid() -- rational only allow valid values, ie
denominator() != 0
2. rational.denominator() == 0 -- always false
3. rational.denominator() < 0 -- always false but implementation
detail: http://www.boost.org/doc/libs/release/libs/rational/rational.html#Internal%20representation
* Simplified code that relies on:
1. rational.denominator() != 0 -- always true
* BUGS EXIST because Fraction allows the creation of invalid values but
boost::rational throws the exception boost::bad_rational
