Reports a fatal user-space error. Writes "panic: <s>" to the standard error stream, requests host_reboot(RB_DEBUGGER) on the host port previously registered with panic_init (effective only if that is the privileged host port), and then calls abort(); does not return. Despite the printf-like prototype, the current implementation formats only the format string itself and ignores the variadic arguments.
