* 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
Fix#3566
Also update testsuite so that all tests read and write some data. Opening a connection is not enough to trigger connection errors, because the connection is so lazy.
* Add H2C support to server
* update comment
* Make http1.1 ALPN work on SplitHTTP client
Users that encounter protocol version issues will likely try to set the
ALPN explicitly. In that case we should simply grant their wish, because
the intent is obvious.
