From: Chris Wulff <crwulff@xxxxxxxxx>
Add the ability to create c_alt.x and p_alt.x directories to
have different configurations for channels/sample size/sync mode. This
patch only implements the user interface and does not yet alter the
behavior of the function.
Initial values for the alt mode settings are copied from the main settings
at the time the alt mode directory is created.
