Revert "Use a per-thread array" This reverts commit 800410eef1c0811 and instead increases stack size. I went through the old emails with Daylen that reported the crash issue on Mac OS X and was fixed by 0049d3f337b6f3a66a0. It was reported default stack size for a thread in Mac OS X is 8 megabytes while the patch that we are reverting allows to reduce stack size at max of about 217KB, so the reason for the crash was only marginal in MAX_MOVES value. On those emails Daylen also hinted how to increase stack size for Mac OS X to 16MB. So prefer to increase stack size to 16MB instad of re-inventing the wheel and do our home grown stack as we did with the patch that we are now reverting (it will remain anyhow in git history for documentation purposes). No functional change.
