release v0.8.1
socket close fd when auth failed
accept may not start fd, so it can't close at last
fprintf need cr
fix issue #200
dispatch read before write, and try to dispath both
support user defined send object
add UDP support, and TCP listen support ipv6 now
use fork to dispatch more socket message
If recv one udp message, try read next immediately rather than until next epoll_wait
remove unused code
add snax.self and snax.exit
remove snax queue mode
bugfix: use ai_list instead of ai_hints
bugfix: init should be out
use snax.newservice would be better
