This aligns with strace, and is very useful when tracing multi-threaded programs. The result is the same in single-threaded programs.
See also "-D log.%d -d tid -strace" which will split the output into per-tid files.
gettid() requires the _GNU_SOURCE feature test macro, so it might be unavailable in rare cases. I don't expect it to be a problem though, because it's implemented by both glibc and musl.

Probably better as qemu_get_thread_id(), but otherwise Reviewed-by: Richard Henderson <richard.hender...@linaro.org> r~
