No sensor access to idle UIDs - native framework
Idle UIDs are ones that were in the background for long enough time.
Currently such apps can access sensor data even though they have no
user perceptible components running. This affects the user's privacy
since an app in the background can use sensor data to infer location,
activity, habits, etc.
The goal is to restrict sensor access for all apps in the ecosystem
regardless of target SDK which means the solution should be backwards
compatible. At the high level the sesnor service observes UID state
changes and applies policy like this:
Continuous sensors: for sensros in this reporting mode when the UID
goes in the background we will stop dispatching events. Once the UID
goes active we will start reporting the events. While this is an
app visible behavior change we would rather do that vs delivering
fake events.
Flush events: there is no change in behavior based on the UID state.
Hence, idle apps can request a flush and would get the completion
callback. From an app perspective flushing works at any point.
Trigger events: for sensors in this reporting mode when the UID
goes in the background we will not report any trigger events. From
an app perspective the sensor just did not pick up any events.
On-change events: for sensors in this reporting mode when the UID
goes in the background we will not report any change events. From
an app perspective the sensor just did not pick up any events.
Wake locks: since UIDs in idle state cannot acquire wakelocks we
will not be grabbing a wakelock on behalf of apps in that state.
Test: Added - SensorTest#testSanitizedContinuousEventsUidIdle
Added - SensorTest#testBatchAndFlushUidIdle
Pass - cts-tradefed run cts-dev -m CtsSensorTestCases

Check key before edit value in countFlushCompleteEventsLocked
Fix an unchecked editValueFor that potentially causes log fatal
when sensor is removed from connection shortly before arrival of
flush complete message.
Bug: 62806749
Test: compiles, flush() still working.

Direct report mode support in sensor service and client
Added SensorDirectConnection to represent the direct channel.
The life-cycle is similar to that of SensorEventConnection.
Modified SensorDevice and SensorDeviceTreble to support new
HAL API. Added support in SensorManager, SensorService, binder
classes. Also added related helper functions in Sensor and dumpsys
support in SensorList.
Test: manual test with demo app

sensorservice: switch to use sp<> in sensor list
* Switch to use smart pointer in SensorList to avoid object
life cycle issue.
* Refactor HardwareSensor and various virtual sensor class.
* Change active virtual sensor map into a set of handles.

Divide huge SensorService files into managable pieces
Splitted SensorService.cpp and SensorService.h into smaller more
manageable pieces with the embedded classes/structs now in individual
files.
