rtspsrc: Use URI hash for stream id

rtspsrc currently extracts an upstream stream-id and appends some session description meta. When upstream elements like udpsrc generate a random id, sometimes they are not unique. This causes issues in muxing/demuxing in funnel/streamiddemux.

This MR proposes a change in which the upstream id is ignored and the new generated stream-id consists of a RTSP URI hash and the appended SDP meta.

changed the description

Might be worth mentioning in the commit message that this is already the behaviour for TCP/interleaved and only makes it the same for UDP now.

Looks good to me otherwise, thanks!
