- IPC socket: add REUSEADDR when using IP (remove comment)

- Test: remove variable to use backend restconf, since that is the only option
- Docs C-style: describe return values better

 All function returns that have return values must be checked
 
 Default return values form a function are:
-0:  OK
--1: Fatal Error

 In some cases, Clixon uses three-value returns as follows:
