 * read_config()
 *
 * DESCRIPTION: Read the lines in a configuration file and return the
 *		pairs of devices to be mirrored/enabled/disabled/updated.
 *		The format for the configuration file is as follows:
 *
 *		fromhost fromfile frombitmap tohost tofile tobitmap
 *
 *		where fromfile is the primary device which is local to the
 *		fromhost subsystem, tofile is the secondary device which is
 *		local to the tohost subsystem, and type is 1 if the device
 *		a simckd device or 0 otherwise.  Any line preceeded by a '#'
 *		is considered to be a comment.
 *
 * Inputs:
 *	char *config_file	Name of configuration file for rdcadm
 *
 * Outputs:
 *	int i			Number of pairs of devices
 *
 * Side Effects: The 0 to i-1 entries in the pair_list are filled.
 *
