error: Simplify error sink setup
qemu_error_sink can either point to a monitor or a file. In practice, it always points to the current monitor if we have one, else to stderr. Simply route errors to the current monitor or else to stderr, and remove qemu_error_sink along with the functions to control it. Actually, the old code switches the sink slightly later, in handle_user_command() and handle_qmp_command(), than it gets switched now, implicitly, by setting the current monitor in monitor_read() and monitor_control_read(). Likewise, it switches back slightly earlier (same places). Doesn't make a difference, because there are no calls of qemu_error() in between.
