echocan: Improve interface for echo cancelers.
Echo cancelers are now able to report if they are able to automatically disable
their NLP portions in the presence of tones in the audio stream. Also, the
interface is changed to allow user space to just disable the NLP portion of the
echo canceler. These changes improve fax and modem handling in DAHDI.
