Adam Cozzette 3d2ed0d410 Updated the generator to fully qualify std::string
The protobuf common.h header currently has a "using std::string;"
statement that pulls std::string into the google::protobuf namespace:
ce66f6047d/src/google/protobuf/stubs/common.h (L195)

I plan to delete that line soon. To keep protobuf-c working, this commit
updates the generator to fully qualify std::string.
