Put a specific comment marker next to every piece of code that MSVC gives warning 4996 for. This warning is generated for calls to functions that Microsoft considers insecure or deprecated. This change is in preparation for fixing all these cases even though none of them are actually incorrect or insecure as used in qpdf. The comment marker makes them easier to find so they can be fixed in subsequent commits.
