Summary: Fix build with --enable-c++11 on FreeBSD

Initial Comment:
On FreeBSD, the definition of NULL depends on the version of the C++ standard used. When building C++03 code, NULL is defined to 0. When building C++11 code, it is defined to nullptr instead. This behaviour is allowed by the standard.

ScummVM has a couple pieces of code, where a null pointer is being cast to an integer type. When building ScummVM as C++03, this works, as it simply yields integer 0. In C++11 mode, this causes the build to fail.

Furthermore, there are several pieces of code in ScummVM that use anonymous structs/unions. This causes Clang to print compiler warnings, as anonymous structs/unions are not part of the standard. This is not addressed by this patch.
