Title: Feature/go hci v3

V3 addresses most of the comments in previous revisions, except those related to interface between packages, such as
* conn.go: io.ReadWriterCloser()
* advertiser interface between hci, server, l2cap.

TODO: docs, test, internal packages

Note:
It requires linux kernel v3.14+ for the new USER_CHANNEL of HCI socket.
When a device is opened with user channel, it requires exclusive usage of the HCI interface.
So the HCI interface must be in "DOWN" status, or -EBUSY is returned.

ex: sudo hciconfig hci0 down
