limit hasingestpoint and streamalias on socket

i propose to enable/disable the option/features "ingesstpoint" and "streamalias" per acceptor/socket and not global. Both feature will be very usefull in lot of cases for incoming and outgoing connections but generate a lot of extra work for features like recording and transcoding, as a streamalias make to be available before starting recording/transcoding. In case of "reboot" the streamalias is not existing anymore and recording (and transcoding) will not continue. As well additonal datahandling is required to define a onetime streamalias to be able to record. Additonal and switching of streamalias on/off will influence the commands required for recording&transcoding. regards, Uwe
