libuv
Most features of libuv are supported by current port, except SIGPROF relative function (loop_configure).
Nearly full libuv's test suite avaliable on NuttX, but some known case can't run on sim:
- loop_update_time
- idle_starvation
- signal_multiple_loops
- signal_pending_on_close
- metrics_idle_time
- metrics_idle_time_thread
- metrics_idle_time_zero
And some will cause crash by some reason:
- fs_poll_ref
