Stream.I.Media: Replace the Paused FlowState with Muted

Paused doesn't meant anything in the context of a live stream. It's not different from Stop.

And we miss a way to tell the streaming implementation to send blank data. This is important for two cases:

1. Privacy: if you're sending SRTP, you don't want someone who sees the data on the network to know if you're talking or not.

2. WMM: if you are WMM, you don't get timely incoming packets unless you have outgoing packets. The easy way to send silence on mute.
