[PATCH v2 04/14] app/test-pmd: use portable variadic macros

[Andre Muezerie]

Many places are using a GCC extension related to variadic macros,
where a name prepends the ellipsis. This results in a warning like
the one below when compiling the code with MSVC:

app\test-pmd\testpmd.h(1314): error C2608:
    invalid token '...' in macro parameter list

Variadic macros became a standard part of the C language with C99.
GCC, Clang and MSVC handle them properly.

The fix is to remove the prefix name (args... becomes ...) and use
__VA_ARGS__.
