The stream handler assumed all HTTP headers contained exactly one space, but the standard says there may be zero or more. Should fix Bug #47021, and any other edge cases caused by a web server sending unusual spacing, e.g. the MIME type discovered from Content-Type: can no longer contain leading whitespace. We strip trailing whitespace from the headers added into $http_response_header as well.
