[radsecproxy] C99 dialect for radsecproxy

Hi All, I'm currently working on pull-request #72. This uses some language features of C99 to make the code somewhat more readable (previously, all code was C90 style). Enabling C99 style should not be an issue for modern systems (even down to Debian jessie). But: is anyone out there using a compiler that won't support C99 dialect?
