(This is a merge of http://go/wvgerrit/76063) Now that we have C++11, many places that do string formatting or parsing can be replaced with std::to_string() or one of the std::sto*() family of functions. This patch updates places that do simple stringifying or parsing to use these functions. Some parts of the code are left untouched because they were using StringStream to do more complex actions, such as constructing more complex output or checking the status of the parsing.
