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.

only supports that mode. However, when the function for doing array-style updates was written, the argument names were reversed. In Zaptel this did no harm, because HPEC was the only module that used array-style updates.
When DAHDI was created, non-array-style updates were removed, and the existing modules were converted to using array-style updates. Unfortunately the new code was written based on the argument names, which were incorrect. This caused all the echo cancellers to be broken (except HPEC, although we did not know that at the time), and it was corrected by reversing the order of the arguments passed when the array-style update function was called (leading to a confusing mismatch). This fixed all the non-HPEC modules, but left HPEC broken, which was just discovered.
This commit corrects all these problems, so that the argument names and the data passed actually make sense, and all the modules work properly.

checking tool. some of these fixes are non-optimal (casting 'unsigned long' to '__user void *'), but are unavoidable in many cases. started from tzafrir's patch, did most of the work myself.

minor fixes and improvements... seems to work properly, except the usecount on the echocan modules never increments above zero, so they are unloadable when they should not be
