/*
**  CM_CLEANUP -- cleanup after interrupt or error.
**
**	This routine does things like call the interrupt cleanup
**	function, reset the input, etc.
**
**	Parameters:
**		typ -- the type of cleanup:
**			1 -- fatal error (from error [error.c]).
**			2 -- keyboard interrupt.
**
**	Returns:
**		never (uses non-local jump to ctlmod/main.c).
**
**	Side Effects:
**		Proc_name & Cm.cm_input are reset.
**
**	Trace Flags:
**		0
