r->headers_in is shared by original requests and components (make no sense

copy them for components), but each component has its own r->pool.
So once the first component set "Max-Forwards", it is in headers_in
but the value could get lost with the first component's r->pool.
Hence I sometimes see "Max-Forwards" has value like letter "l".
Change it to use apr_table_set() fixed the problem.
