Unlike kqueue/kevent of BSD, the epoll of Linux could be add/del by using different API on the fly. This patch drops the notify used by mevent_add/del and call epoll_ctl to add/delete target fd. Only keeps global_head to track mevent added and makes the code logic in mevent_dispatch() a littel bit simpler. Another thing is related with epoll_ctl. If the target fd is regular fd which doesn't support epoll, epoll_ctl will return -1. When DM is start by systemd, the STDIO is not mapped to terminal, epoll_ctl on STDIO could return -1. Which block UOS boot. We only call mevent_add after confirm STDIO is mapped to terminal.

ACRN Device Model
#################
Introduction
============
The ACRN Device Model provides **device sharing** capabilities between the Service OS and Guest OSs. It is a component that is used in conjunction with the `ACRN Hypervisor`_ and this is installed within the Service OS. You can find out more about Project ACRN on the `Project ACRN documentation`_ website.
