Bound the pending write events queue to a large amount of events in
total (100,000) so that we do not have out of memory crashes when the
sensors framework locks up. Events are 80B of memory each. So this
change caps are pending writes event queue to 8MB of memory.

C++20 will require members in a designated initializer to be in order
unlike C99.
This snuck in because I haven't upgraded the platform toolchain yet.

The multihal framework is a HAL interface for the sensors framework that
allows multiple vendors to package their HAL implementation into a
subHAL dynamic library that will be loaded and used to pass on method
calls to the appropriate subHAL. The HalProxy object, that will act as
the main proxy sensors wrapper for the multiHAL handles writing sensor
events to the event FMQ and wakelock acquisition and releasing via a
callback object it passes to the subHALs.
In order to turn your HAL 2.0 executable into a subHAL to be used by the
multiHAL, implement the Return<Result> initialize(sp<HalProxyCallback>&
callback) method of the ISensorsSubHal derived class. Implement the
ISensorsSubHal* sensorsHalGetSubHal(uint32_t* version)method and have it
return a pointer to your subHAL object. Build this into a dynamic
library and list its filename under /vendor/etc/sensors/hals.conf.

Fix bug where the HalProxyCallback::postEvents method was passing the
unaltered events vector to HalProxy::postEventsToMessageQueue instead of
the processedEvents with altered sensorHandles. Add a unit test to test
that the proper sensorHandles are seen compared to the event posted from
subhal.
Additionally, fix problems with fake subhals and their dummy sensors
that allows VTS tests to pass all tests.
Bug: 136511617
Test: New unit tests pass and VTS tests under module
VtsHalSensorsV2_0Target passing.

For each HalProxy method that takes in a sensorHandle, the code now
checks that the subhal index byte (first byte) of the handle is the
range of subhals in list before indexing into mSubHalList so that are
crash does not occur and returns Result::BAD_VALUE if that is the case.
Add unit tests to assert that error is returned. Also change the methods
that accept sensorHandles to int32_t type since that is the actual type
defined in the HAL spec.
Bug: 136511617
Test: Passing new unit tests.

Spin up a background thread inside the hal proxy that is responsible for
writing events to the event fmq if a previous write failed on the normal
postEvents thread. Create several new unit tests that help test the new
functionality.

Test: Compiles successfully. Simple enough change to ignore unit tests
for now.

Put the ScopedWakelock class into its own header and its implementation
into its own cpp. Implement the refcounting of the wakelocks. However,
do not incorporate the wakelock handling into post events in halproxy
yet.
Bug: 136511617
Test: No new tests yet. Will add more in a later patchset once more
fleshed out and integrated with postEvents.
Change-Id: I0815c6a6659ec5933b799294956595b11e7bf1b3
Add post events method to HalProxyCallback without fully implementing
the wakeup events handling and pending blocking writes. Also change
mSensorList of the halProxy to mSensors which is a map from sensorHandle
to sensorInfo so that getNumWakeupEvents method of callback can find
sensorinfo info from sensorhandle of event type. Instantiate
halproxycallback vector in HalProxy for each subhal in the ctor as well.
Add very simple test for the postEvents method of callback.
Bug: 136511617
Test: New unit test passes.

there. Also use the constant in initSensorsList method.

Implement setOperationMode method of HalProxy object and initialized the
direct channel flag for the sensors list. Also create some unit tests to
test both of these new additions in HalProxy_test.cpp.
Bug: 136511617
Test: Tested using unit tests and tested on device with both fake
subhals
Change-Id: I4e39ca0e94b3e109706d628612d1db9c98aca053
Implement SubHal constructors. The default ctor will get the SubHal
object pointers from dynamic libraries. The test ctor will take a vector
of SubHal objects. Implment the HalProxy getSensorsList method which
will return all the sensors from the subhal objects. Create one unit
test for getSensorsList as well.
Bug: 136511617
Test: Flashed onto device and observed proper logs for both test
subhals. Also, passed getSensorsList test.

Sets up a unit test file that can be used to unit test the HalProxy. The
unit tests will eventually end up containing code that injects the fake
SensorsSubHal implementation into the HalProxy and verifies various
parts of the implementation. This will likely require some modifications
to the SensorsSubHal class to modify it during test execution, but it's
better that the same implementation is shared between unit / manual
integration testing.

Creates a fake sub-HAL using the default implementation for sensors HAL
2.0 with some small modifications to support the multi-HAL interface.
This sub-HAL can be configured to support two different sets of sensors
making it easier to build and load two different sub-HAL implementations
onto device and verify the multihal implementation works.
Bug: 136511617
Test: compile only. Once multihal can load in sub-HALs, then this can be
accurately tested.
Change-Id: I9b136506bdbc8a3b196fd363748bddfcdd564daf
Creates a basic set of structures needed to implement multihal 2.0.
Descriptions of each are as follows:
HalProxy - Main point of contact from the sensors framework. Implements
the ISensors interface and will implement several callbacks passed to
sub-HALs in the future
SubHal - Contains interface that sub-HALs are expected to implement in
order to be loaded properly by the HalProxy. Also contains definitions
for various callbacks and classes that will be fully implemented by the
HalProxy.
service.cpp - contains the main function that is reponsible for
initializing the HalProxy and starting the thread pool that will handle
communication between the HalProxy and sensors framework.
Bug: 136511617
Test: compile for now. Stubbed out sub-HAL to be added in a followup CL
to facilitate testing before a vendor implements the subHAL
interface.
