[mcip-list] Patch: new feature: mcipd TCP server bind

[Markus L. <de...@ma...>]

Hi list,

attached a patch with the following content
 
- added feature:
  mcipd TCP server is now able to listen only
  on one interface, e.g. enp1s10 (checkout new parameter 'TCP_bind'
  within docs/mcip.conf). If you want to listen on all
  interfaces just leave the new value blank.

- refactoring:
  moved config specific functions from util.c into new file config.c
 
- refactoring:
  moved config specific variables into one struct

feature add and refactoring within one commit, shame on me...

----
ciao
 Markus
