Bounded copy buffer among streams & goroutine optimization

1. Under *nix, all tcp connections multiplexed on a single kcp connection via smux now share ONE buffer, instead of one buffer per one tcp connection previously. https://github.com/xtaci/kcptun/blob/master/generic/rawcopy_unix.go
2. Eliminated ONE extra goroutine per connection.
3. Fixed a possible error in smux.
