BUG Use epsilon threshold in `_samme_proba` and `_boost_real`
...
Instead of thresholding <0 probabilities to 1e-5, threshold <epsilon to epsilon. This avoids the issue of, e.g., probability values of 0 becoming larger than values of 1e-7.
Add a unit test for `_samme_proba` which checks that probability ordering is unchanged.
Resolves issue #4944 .

TST + PY3 various fixes
...
* Little hack in fixes.py that can be removed when NumPy's
https://github.com/numpy/numpy/issues/3484 is fixed.
* Little cleanup to the fixes implementation.
* Change the numpy workaround and added a test. Fixed some xrange usage.
* Fix the weight boosting test.
* None is not comparable in python3
* Fix a test that depended on dictionary iteration order.
* Python3 removed execfile
* More test fixes.
Fixes #2122 .
