This diff moves and renames the defines that define the maximum number of parallel requests for http and rsync. The defines are now MAX_HTTP_REQUESTS and MAX_RSYNC_REQUESTS the values remane the same. Also move the memset of pollfd sets in http.c into the loop. It is not needed but I prefer it that way.
