SplitHTTP: More range options, change defaults, enforce maxUploadSize, fix querystring behavior (#3603)
* maxUploadSize and maxConcurrentUploads can now be ranges on the client * maxUploadSize is now enforced on the server * the default of maxUploadSize is 2MB on the server, and 1MB on the client * the default of maxConcurrentUploads is 200 on the server, and 100 on the client * ranges on the server are treated as a single number. if server is configured as `"1-2"`, server will enforce `2` * querystrings in `path` are now handled correctly
