Partial implementation of N3665. This paper was not voted into the C++1y draft. However I was looking at it and with some experimentation realized that I could partially implement it, and at the same time offer a performance optimization to cout. I simply added an xsputn override to the cout filebuf. The override does nothing special at all if there is a non-trivial codecvt installed. However if the codecvt returns true for always_noconv(), then this function can dump an entire string to fwrite, instead of doing it a character at a time under overflow(). This just makes sense. I stopped short of a full implementation of N3665 because in order to do so, xsputn would have to allocate a buffer when always_noconv() returned false, and I don't want to go to that expense.

This is an optimization which produces improved launching time. There should be no functionality change. Clients should see no ABI differences.

This SO question: http://stackoverflow.com/questions/15344402/how-can-i-read-a-0xff-in-a-file-with-libc-istream-iterator/15347225#15347225 highlighted the lack of a cast in the implementation of std::cin. Added. I unfortunately don't have a test case to add to the suite since this bug only shows itself when using std::cin. The current testsuite setup does not have a way a good way to test std::cin.

Chris Jefferson noted many places where function calls needed to be qualified (thanks Chris).
