The language server needs stdin, and for tests we should be passing it around. My intent is to pass in a faux stdin to Driver for language server tests. As long as I'm adding a new parameter, I was looking at also changing the way streams are passed in to Driver for style (pointers since they're held past construction lifetime). Since these are all stored in DriverEnv, I thought it might be a net improvement to use the struct directly, getting more explicit parameter names and also removing the need for `SetFuzzing`. I'm trying here to avoid functional changes, but there are a couple additional fixes like removing an obsolete `find_insensitive` and refactoring how `ValidateOptions` handles errors (because it reduces the number of spots that operate on error_stream).
