This file contains a lot of code that doesn't compile for Xbox One and doesn't appear to be necessary for usage on that platform. _WIN32 is defined for the Xbox One platform.
It appears this file was including winsock2.h just to get the timeval struct definition. There are platforms, such as Xbox One, that don't use winsock but do compile with _MSC_VER set, so just drop in the struct definition we needed instead of including all of winsock. This fixes compilation of this file for Xbox One. Without this change, there were numerous `timeval` complaints such as
```

Some compilers, such as PS4's clang, were giving errors such as:
C:\dev\protobuf\src\google/protobuf/parse_context.h(227,5): error : no type named 'uintptr_t' in namespace 'std'; did you mean simply 'uintptr_t'?
Adding the necessary include for integer types fixes these.
All bazel crosstools automatically pass -Wall to compiles. The order of
operations is:
- bazel crosstool flags
- `--host_copt` flags and other variations like `--host_cxxopt`
- the `copts` defined on the rule
Because of this when protobuf produces warnings, there's no way to
disable them from the consumer side if they are re-enabled later by
another `-Wall` flag.
GCC 8 added a -Wclass-memaccess that is enabled in -Wall that warns when
making direct memory modifications to non-trivial objects. The objects
that are modified here are only "non-trivial" in non-interesting ways
(e.g., removal of copy constructor) and can be safely modified as is
being done.
This simply explicitly casts the pointers before calling memset to
indicate that they should be treated as raw memory.
