This update ensures that the Redis state for live channels is correctly cleared when a buffering-timeout failover occurs. Previously, the in-memory buffering flag could be cleared without updating Redis, leading to incorrect state reporting. The fix modifies the logic to clear the Redis state to 'active' when the buffering flag is reset, preventing stale 'buffering' states from persisting after recovery. Tests have been updated to validate this behavior.
- Enhanced the live proxy to release geventpool DB connections more effectively across various paths.
- Implemented `close_old_connections()` in `stream_ts()`, `generate_stream_url()`, `get_stream_info_for_switch()`, `get_alternate_streams()`, `get_connections_left()`, and the cleanup process in `StreamGenerator`, ensuring that clients do not hold onto pool slots unnecessarily during streaming operations.
