olly b563b82787 Add HttpUtil for tasks common to HttpDataSource implementations ... Part of aligning HttpDataSource behavior will require adding logic that's common across the DataSource implementations. This change establishes a util class to house it, and moves a bit of existing logic that's related and can be easily shared into it. There is one small behavior change in this CL, which is that our handling of Content-Range response headers can now parse the body length if the "document size" part of the Content-Range is unknown, for example "bytes 5-9/*". Previously the pattern we were matching to required the "size" part to be set, for example "bytes 5-9/100", despite the fact we don't need or use it.
