Simplify TT interface and avoid changing TT info This commit builds on the work and ideas of #5345, #5348, and #5364. Place as much as possible of the TT implementation in tt.cpp, rather than in the header. Some commentary is added to better document the public interface. Fix the search read-TT races, or at least contain them to within TT methods only.
