This patch introduces common OOC stream processing functions such as `mapOOC(in, out, mapper)` and `joinOOC(in1, in2, out, mapper, joinOn)`. It transitions to a non-blocking, item based scheduling model to eliminate blocking on dequeue operations. To support this, a subscriber system for `LocalTaskQueue` has been implemented. To enable parallel processing of `ResettableStream`, a new `CachingStream` (replacing `ResettableStream`) and corresponding `PlaybackStream` are introduced. This design decouples cache storage from playback, allowing multiple concurrent playbacks over a shared stream. When a `CachingStream` is used, `getStreamHandle()` now returns a new `PlaybackStream` if a `CachingStream` is present. -- This is an automated message from the Apache Git Service.
