As the type of pthread_t is unsigned long, so the init value for it
should not be '-1'. When the tid is '-1', it will continue to call
pthread_kill/pthread_join. This is incorrect.

Supply a decidate thread, which can moniter a set of fds with epoll,
when the data is ready, call the corresponding callback.
This iothread will be created automatically with the first successful
call to iothread_add, and will be destroyed in iothread_deinit if it
was created.
Note, currenlty only support one iothread.
