Add a few missing events to analog_handle_event.

The reported bug was actually only for pulsedigit, dtmfup, and dtmfdown
handling. Also added recognition for fax events (just some verbose output) and
fixed handling for the ec_disabled_event. In order to make comparing the analog
version of events to the DAHDI events easier, the ordering has been changed to
follow that of the DAHDI events.
