If set to true (default) a HWEC, if available on the channel, takes
priority over any software echocan configured in /etc/dahdi/system.conf.
This has historically been the default behavior in all released versions
of DAHDI that support module echocans.
Otherwise, hwec_overrides_swec is set to false, HWEC is chosen only via
the "echocanceller=hwec" directive.
