Restore deterministic search state Introduce helper function Search::reset() which clears all kind of search memory, in order to restore a deterministic search state. Generalize TT.clear() into Search::reset() for the following use cases: - bench: needed to guarantee deterministic bench (ie. if you call bench from interactive command line twice in a row you get the same value). - Clear Hash: restore clean search state, which is the purpose of this button. - ucinewgame: ditto. No functional change. Resolves #346
