[sheepdog] [PATCH 3/4] sheep: take truns to monitor EPOLLIN and EPOLLOUT events.

[Yunkai Zhang]

From: Yunkai Zhang <qiushu.zyk at taobao.com>

When both EPOLLIN and EPOLLOUT events occur, client_hander() will always
process EPOLLIN event firstly, but this is not reasonable in some case.

The simplest way to fix this problem is that, let sheep take truns to
monitor EPOLLIN and EPOLLIUT events.
