Send a system notification when a networking operation is likely
going to be related to media playback.
For now the heuristic is rather primitive: if we have an active source buffer
linked to a media element we assume that all further networking operation in the
page is media related.
The notification is produced by the UI process whenever a content process
has an active source buffers, and when all have been deleted.
