(open_hook, trivfs_modify_stat, trivfs_S_fys_syncfs): Copy DEVICE before using it, so it doesn't change underneath us.

(clean_exit, ports_no_hard_ports): Use close_device. (main): Use trivfs_startup instead of doing it manually. (trivfs_goaway): Try and do it better, paying attention to flags, etc.; this still isn't right though, we may want to wait for the ports library to be fixed first. (DEBUG): New macro, executes its arg with debug_lock locked.
