3 people 8dd7e2041e Cache the thread id per thread on Linux (#236) ...

plat_thread_id made a gettid syscall on every call, and plat_rmutex_lock
calls it on every acquire: about 685,000 syscalls a second in the open
world on 1.4.3. A thread's id never changes and the runtime starts child
processes with posix_spawn only, so the id now comes from a __thread cache
after the first call. Windows is unchanged: GetCurrentThreadId reads the TEB.

Found, measured and fixed by H.A. Forster in issue #236 (RTX 2060 laptop:
36.3 to 46.0 fps with replay_async). SchulzCode confirmed it on an RTX 2070
Super with a 7800X3D: 98 to 120 fps at game resolution, 76 to 90 fps at
render_scale 150.
