Commit ID 2dbb44e28d2e5b3c72ddbbd6f436d41f75031a22

Fix nodestime 1. The current time management system utilizes limits.inc and limits.time, which can represent either milliseconds or node count, depending on whether the nodestime option is active. There have been several modifications which brought Elo gain for typical uses (i.e. real-time matches), however some of these changes overlooked such distinction. This patch adjusts constants and multiplication/division to more accurately simulate real TC conditions when nodestime is used. 2. The advance_nodes_time function has a bug that can extend the time limit when availableNodes reaches exact zero. This patch fixes the bug by initializing the variable to -1 and make sure it does not go below zero. 3. elapsed_time function is newly introduced to print PV in the UCI output based on real time. This makes PV output more consistent with the behavior of trivial use cases. closes https://github.com/official-stockfish/Stockfish/pull/5186 No functional changes
