/*
 *  This is a configuration daemon for the SL-MUX multiplexing driver.  Its purpose is to open
 *  Signalling Link streams on various drivers, attach them to specific PPAs, and link the SL
 *  streams under the SL-MUX multiplexing driver, configure each SL lower multiplex Stream, and then
 *  wait in the background listening for management events on a management stream.  Also, the daemon
 *  watches for updates for the configuration file and applies the updates as they occur.
 *
 *  The daemon is intended to run at system startup from a System V init script.  Once the
 *  configuration of the SL-MUX multiplexing driver is complete, applications programs can open,
 *  attach, enable and use Signalling Link streams opened on the driver.
 *
 *  The purpose of the SL-MUX driver is to provide a unified interface for accessing signalling
 *  links of a number of forms and from a number of various drivers.  Signalling links could
 *  correspond to device drivers, or could be M2UA or M2PA signalling links, or other
 *  implementations.  M2PA signalling links require some additional configuration before they can be
 *  used and will be linked under the SL-MUX by a separate M2PA configuration daemon.
 *
 *  Another possibility is to implement plugable dlopened modules for various devices.  A plugable
 *  module would define its own syntax for the last fields in the configuration file entry (after
 *  the selector).  New selectors could then be defined.
