Try to suppress MSVC++ unused parameter warnings.
I haven't found a way to with MSVC to mark parameters in the argument list as unused. MSVC doesn't give warnings about them in C code, but does appear to give them with C++ code. An answer to http://stackoverflow.com/questions/3020584/avoid-warning-unreferenced-formal-parameter suggests not giving the formal parameter a name in C++. Have a macro UNUSED_PARAMETER(), which takes as an argument a variable name, and expands to nothing in C++ and to the variable name followed by _U_ in C, and use that for some unused parameters. If it works, we'll use it for all of them. Change-Id: I76107bed037f1f0d94615adb42234c9faf83b4db Reviewed-on: https://code.wireshark.org/review/4016 Reviewed-by: Guy Harris <guy@alum.mit.edu>
