orex requested review of this revision.

1. `double log2_eval(double)` function added with better than float precision is added.
2. Some refactoring done to put all auxiliary functions and corresponding data

to one place to reuse the code.

3. Added tests for new functions.
4. Performance and precision tests of the function shows, that it more precise than exiting log2,

(no exceptional cases), but timing is ~5% higer that on current one.
