The implementation of virtio_input_get_config is based on ioctl of

to service configuation request from FE driver:
- name and devids

Input events are read from host evdev fd and cached into a local queue.
When SYN_REPORT is read, the cached input events are sent to guest via
EVENT virtqueue. Guest input events are read from STATUS virtqueue then
written to host evdev fd.

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.
