dahdi-base: Allow HWEC to use the modular echocan interface

Browse Source 
This change adds an echocan factory to dahdi-base that will allow hardware
echo cancellation to use the same interface as the current software echo
cancellers.  The additions in this commit will not have any effect until the
current HWEC mechanism is removed.
