[sr-dev] support for 'include' in cfg file

[Daniel-Constantin Mierla]

Hello,

just committed to GIT support for 'include' in config file. Hopefully 
this helps in nicer structuring and maintenance of your configs.

The syntax is simple:

include path_to_file

The path_to_file can be relative or absolute. If it is not absolute 
path, first attempt is to locate it relative to current directory, and 
if fails, relative to directory of the file that includes it. There is 
no restriction where include can be used or what can contain - any part 
of config file is ok. There is a limit of maximum 10 includes in depth, 
otherwise you can use as many includes as you want. Reporting of the cfg 
file syntax errors prints now the file name for easier troubleshooting.
Example:

route {
     ...
     include /sr/checks.cfg
     ...
}

--- /sr/checks.cfg ---

    if (!mf_process_maxfwd_header("10")) {
        sl_send_reply("483","Too Many Hops");
        exit;
    }

---

Testing and feedback is much appreciated.

Cheers,
Daniel
