Remove get_nanoseconds_clock as we'll rely on std::chrono's high

resolution clock for this in C++11. Now that the only remaining
function in time.h is calendar_point, rename the header to
calendar.h. Hopefully that last use will go away once a TR2 datetime
library becomes available.

Use std::chrono inside the library benchmark code.
