This patch creates a HostInfo class, a static class used to answer basic queries about the host platform. As part of this change, some functionality is moved from Host to HostInfo, and relevant fixups are performed in the rest of the codebase. This is part of a larger effort to isolate more code in the Host layer into platform-specific groups, to make it easier to make platform specific changes for a particular Host without breaking other hosts.
