#include <string> for std::wstring.

It looks like you're mixing some string16 with wstring here. Maybe it should
take std::string here, and have the caller do either WideToUTF8 or UTF16ToUTF8
depending on what it's got.

Alternatively, you can do...
static int64_t HashDeviceName(const wchar_t* device_name);

This is a similar change I've got in an in progress CL.

Done. I went with Scott's suggestion, since display.cc is not dealing with
wchar_t* here.
