web server: do not provide a response body where it is not permitted
* module/web/response.scm (response-must-not-include-body?): New
function.
* doc/ref/web.texi: Doc the function.
* module/web/server.scm (sanitize-response): Error if we have a body,
but the response type does not permit a body. If we are responding to
a HEAD request, silently drop the body.
