Shaun Ruffell 25ce85e770 dahdi: Filter 'HWEC' from DAHDI_GETVERSION results if hwec is really not present. ... Internally in DAHDI there is always a hardware echocan factory registered and available. Having this factory always registered allows for DAHDI to work in a backward compatible fashion. Namely, by default DAHDI will always use a hardware echocan if one is available unless 'hwec_overrides_swec' dahdi module parameter is set to 0 on load. However, if there were no real hardware echocans available in the system dahdi would still report "Echo Canceller(s): HWEC" in the dahdi_cfg -v output since the hwec factory is always there. After this change dahdi_cfg will no longer report HWEC as one of the available echocans if there isn't a physical span present that actually has a hardware echocan.
