Beast includes a lot of code for encapsulating cross-platform differences which are not used or needed by rippled. Additionally, a lot of that code implements functionality that is available from the standard library. This moves away from custom implementations of features that the standard library provides and reduces the number of platform-specific interfaces andfeatures that Beast makes available. Highlights include: * Use std:: instead of beast implementations when possible * Reduce the use of beast::String in public interfaces * Remove Windows-specific COM and Registry code * Reduce the public interface of beast::File * Reduce the public interface of beast::SystemStats * Remove unused sysctl/getsysinfo functions * Remove beast::Logger
