Change variadic macros to C99 style.

The macros used GCC's pre-C99 syntax, which could not be compiled with
Microsoft Visual Studio 2008.

Note this breaks compatibility with GCC versions before 3.0, which is
deemed safe in a discussion on IRC with David Sommerseth and Samuli
Seppänen on #openvpn-devel (RHEL 3 uses GCC 3.2 already).

Compiled tested on VS2008 by Samuli, on Cygwin GCC 3.4 and GCC 4.3 by myself.
