Author Joost VandeVondele

Refactor final stats updates. This PR refactors update_quiet_stats, update_capture_stats and search to more clearly reflect what is actually done. Effectively, all stat updates that need to be done after search is finished and a bestmove is found, are collected in a new function ```final_stats_update()```. This shortens our main search routine, and simplifies ```update_quiet_stats```. The latter function is now more easily reusable with fewer arguments, as the handling of ```quietsSearched``` is only needed in ```final_stats_update```. ```update_capture_stats```, which was only called once is now integrated in ```final_stats_update```, which allows for removing a branch and reusing some ```stat_bonus``` calls. The need for refactoring was also suggested by the fact that the comments of ```update_quiet_stats``` and ```update_capture_stats``` were incorrect (e.g. ```update_capture_stats``` was called, correctly, also when the bestmove was a quiet and not a capture). passed non-regression STC: LLR: 2.96 (-2.94,2.94) [-3.00,1.00] Total: 75196 W: 16364 L: 16347 D: 42485 http://tests.stockfishchess.org/tests/view/5db004ec0ebc5902c06db9e1 The diff is most easily readable as ```git diff master --patience``` No functional change
