Add const Keyword to some function parameters in chainimpl.h

[Andreas]

Hi there,


while reviewing the doxygen documentation in this file I found some 
instances where I think the function parameters should be made constant.

Bellow my suggested changes:


commit 9fc61307be4f21039b7cd4553099e29e5fd5e456 (HEAD)

Author: Andreas Dachsberger <andreas.dachsberger at embedded-brains.de>
Date:   Fri Apr 5 08:28:08 2019 +0200

     Added const to function parameters.
