Shaun Ruffell dd33d6c357 dahdi: Update the dahdi_ec_chunk interface to support preec streams. 
dahdi_ec_chunk is the function that saves the received audio and places
a signed linear copy of it in the pre echocanceled buffer on the
channel.  By splitting the input and output of this function into two
parameters, a driver that can provide separate pre and post ec streams
can pass them independently to DAHDI, without worrying about DAHDI
overwriting a stream that may have already been echocanceled by the
hardware.

Previously, the dahdi_ec_chunk interface took a received audio buffer
and overwrote it after canceling the echo.  Now the input and output
from the function are broken up in order to support hardware echocans
that have a different preechocan stream.
