This requires the introduction of the flag B_USER_MUTEX_SHARED, and then actually using the SHARED flags in pthread structures to determine when it should be passed through. This commit still uses wired memory even for per-team contexts. That will change in the next commit. GLTeapot FPS seems about the same.
