Sorry, this is a painful commit to review :( Until now, the only consumer of the PipeWire code is the screen cast portal code. This portal code only ever has one PipeWire connection, and one PipeWire stream, every time a monitor or a window is selected. This is reflected on obs_pipewire, which only handles a single stream for any given connection. For cameras and audio, however, a single PipeWire connection can and most likely always will provide multiple streams. For example, computers with multiple webcams will have one PipeWire connection reporting multiple PipeWire nodes, one node for each camera. This commit breaks this one-stream-per-connection assumption, and makes obs_pipewire_connect_stream() return an independent object (obs_pipewire_stream) that represents a single stream. The screencast portal code continues to only ever have one connection and one stream.
