Remove STHAL 2.4
This version was only created as an intermediate version for
development and was never intended for release. STHAL 3 (AIDL) has
feature-parity with this one and is intended for release.
Bug: 181996624
Test: Manual verification of soundtrigger use-cases.

-/**
- * SoundTrigger HAL interface. Used for hardware recognition of hotwords
- * and other sounds.
- *
- * Important notes about the threading model:
- * ==========================================
- * Both this interface and the corresponding callback interface use a synchronized calling
- * convention. This model comes with some advantages, but also with some risks of deadlocks if the
- * implementation does not handle this correctly. Please consider the following:
- * - After stopRecognition() returns no more recognition events for that model may be sent. This
- * implies that any queues holding such events must be flushed before the call returns and that
- * may imply that callback from the HAL to the client are done while stopRecognition() is blocked.
- * This is OK, and supported by the framework.
- * - Similarly, the same relationship applies between unloadModel() and subsequent callbacks to
- * modelUnloaded().
- * - Other than these two cases, calls into the HAL *MAY NOT* block on callbacks from the HAL, or
- * else deadlock conditions may result, which may be handled by rebooting of the HAL process and
- * cause service outages.
- *
- * Similarly, it is expected that a single call to startRecognition() generates at most one event
- * (the model automatically becomes stopped when the event occurs, until explicitly started again)
- * and that after a modelUnloaded() event no more events would be sent regarding the model.
- * Note that a getModelState() call may generate a recognition event, but this event DOES NOT modify
- * the model state - the model remains started.
- *
- * The HAL is expected to correctly handle a stopRecognition() call even after it sent an event
- * indicating that recognition is stopped and an unloadModel() call even after it sent an event
- * indicating that it has been unloaded. This is required in order to prevent race conditions
- * between these calls. This also implies that model handles should generally not be reused until
- * explicitly unloaded. To avoid the rare possibility of running out of handles, the framework will
- * call unloadModel() on models that have been preemptively unloaded by the HAL.
- *
- * Due to the asynchronous nature of recognition events and preemptive model unloading, the HAL must
- * correctly handle requests that would have been valid before an event has been delivered, but
- * became moot as result of the event. Namely:
- * - stopRecognition() may be called on a model that has already delivered an event and became
- * inactive as a result. The HAL must return a successful return code in this case.
- * - Furthermore, if a model is preemptively unloaded after it triggers (typically, this would
- * happen when it is first aborted and immediately preemptively unloaded), stopRecognition() may
- * be called on it. The HAL must return a successful return code in this case.
- * - startRecognition() may be called on a model that has been preemptively unloaded. In this case,
- * the HAL must return -EBUSY to indicate that the operation is temporarily unsuccessful.
- * - unloadSoundModel() may be called on a model that has been preemptively unloaded. The HAL must
- * return a successful return code in this case.
- *
- * Important notes about resource constraints and concurrency
- * =========================================================
- * Up until this version, the framework would enforce concurrency constraints expressed by the
- * Properties presented by the soundtrigger instance. These include constraints on the maximum
- * amount of models that can be loaded at the same time and on running recognition while capturing
- * from the microphone.
- * This version changes the approach for how these constraints are modeled, both offering the HAL
- * implementation more flexibility and simplifying the framework's job in enforcing these
- * limitations. Note that there is no change for how the framework behaves with earlier versions,
- * everything described below only applies to this version and onward.
- * The way this is achieved is as following:
- * - The framework will no longer enforce constraints on concurrent loading of models, as expressed
- * in the Properties.maxSoundModels field (this property is merely a hint at this point and may be
- * deprecated in the future.
- * - The framework will no longer enforce constraints on concurrency of audio recording and
- * soundtrigger operation, as expressed in the Properties.concurrentCapture field (this property
- * is merely a hint at this point and may be deprecated in the future).
- * - The framework will no longer enforce constraints on concurrent loading of models, as expressed
- * in the Properties (these properties are merely hints at this point and may be deprecated in the
- * future.
- * - The HAL implementation is free to reject starting of any model at any time by having the
- * respective start*() method return -EBUSY.
- * - The HAL implementation is free to reject loading of any model at any time by having the
- * respective load*() method return -EBUSY.
- * - The HAL implementation is free to preemptively stop a previously started model at its own
- * discretion (for example, if a higher priority use-case which cannot coexist with detection
- * has been requested). The HAL must notify the framework of the preemption by sending a
- * recognition event with an `ABORT` status. The implementation must NOT attempt to restart the
- * recognition automatically when conditions change.
- * - The HAL implementation is free to preemptively unload a previously loaded model at its own
- * discretion (for example, if a higher-priority model is being loaded and the two cannot
- * coexist). When doing so, it must first abort the detection if active (as per above) and then
- * notify the framework of the unload using the newly added modelUnloaded callback.
- * - When conditions change, such that a model that couldn't previously load or start or that had
- * previously been preemptively stopped or unloaded, the HAL must notify the framework via the
- * newly added tryAgain() callback. This callback is not a guarantee that any operation would now
- * succeed, but merely a hint that retrying something that had previously failed, now MAY succeed.
- * Until this callback arrives, the framework may assume that any operation that had previously
- * failed or aborted would still fail if retried, so the implementation should not forget to
- * deliver it. There are no guarantees regarding how the framework may respond to this event and
- * the order in which it may choose to reload/restart its models. Typically, as result of this
- * event the framework will make a single attempt per model to bring this model to its desired
- * state (loaded, started).
