Pieter Wuille 747da25360 feefrac: drop comparison and operator{<<,>>} for sorted wrappers ...

Instead of having an unintuitive but total implicit sort order on
FeeFrac (first increasing feerate, then decreasing size), and separate
overloaded operator<< and operator>> for a weak ordering that only looks
at feerate, replace these with explicit wrapper classes which make the
behavior more explicit.

This allows for things like ByRatio{a} <= ByRatio{b}, instead of the
earlier !(a >> b). It also supports usage inside std::max and
std::greater, so one can use:
* std::max<ByRatioNegSize<FeeFrac>>(a, b)
* std::sort(v.begin(), v.end(), std::greater<ByRatioNegSize<FeeFrac>>{})
