Clean up connection to sensor hidl service
getService() would block until hidl service up and running. Replace
retry delay with service registration listener to speed up.
Moreover, when getService() return nullptr, it means sensor hidl
service does not exist. Remove retry in this case and return failure.
Bug: 66916774
Test: test device boot
Test: adb shell "stop; start"
Test: kill sensor hidl process
Test: mod manifest file to remove sensor entry

Double check hidl service at init + meaningful abort when hidl crash
Sensor hidl service will kill itself when it detects
double-connection(*) from framework sensor service in order to avoid
potential deadlock. This cl adds a no-op call to hidl service at
initialization of framework service to allow early detection on hidl
service side. It also adds retry mechanism in this case to avoid
another system server crash.
Log messages is added when hidl call transport failure to help better
identify problem. There is no sane recovery at this point and fatal
log is preferred.
* Double-connection to hidl service happens when framework sensor
service crash but leave a lingering connection in sensor hidl service.
Auto restarted framework service will attempt to connect hidl service
again which result in a double connection.
Test: manually killing sensor hidl service and/or restart runtime,
with and without sensor service in restricted mode, observe
system recover to good state.
Pid of sensor hidl service can be found by lshal
lshal | grep sensor
switch to restrict mode
dumpsys sensorservice restrict a.non-exist.package

SensorService fixes.
1) Flush should only be received by the app calling flush(). Maintain
a queue of all flush() calls and send flush_complete events in that
order.
2) Log warnings for older HALs. Remove batch() calls with DRY_RUN flag.
3) Reallocate event cache when more sensors register and the desired
maxCacheSize increases. Clear NEEDS_ACK flag in the buffer whenever
there is a write() failure.
4) More dump information. Add wake-up flag, maxDelay and timestamps for
sensor events.

improve sensor battery usage tracking
until now we were tracking when a sensors was
physically enabled or disabled and we were reporting
that to the BattaryService.
this wasn incorrect because we could have several different
apps enabling the same sensor, so the accounting by the
battery service would be incorrect in that case (depending
on the order in which these apps disabled said sensor).
BatteryService tracks sensors per uid, however SensorService
does this per binder connection, so we could have several
binder connections for the same uid, to solve this we keep
a list of sensor/uid -> count, which is the bulk of this
change.

handle EINTR when calling sensor HAL's poll function
some sensor HALs don't handle EINTR, make sure to catch it in the
sensorservice.
also if we ever encounter an error that we can't handle, we abort
which will restart us (or the whole system process if we're running
in it)

fix [3237242] sensormanager sensor active count gets out of sync
whether a physical sensor needed to be active or not was managed by
a simpe reference counter; unfortunatelly nothing prevented it to
get out of sync if a sensor was disabled more than once.
sensorservice already maintainted a list of all the "clients"
connected to a physical sensor; we now use that list to determine if
a sensor should be enabled. This can never be "out-of-sync" since
this is the only data structure linking a sensor to a user of that
sensor.
also removed the isEnabled() method, which was never used and
implemented wrongly (since it didn't take into account that a sensor
could be disabled for a client but not of another).

Add support for virtual sensors.
Rework sensorservice to allow "virtual sensors", that is
sensors that report a synthetized value based on real sensors.
the main change to sensorservice is around managing which real
sensor need to be activated and which rate to use.
The logic for all this has been moved into SensorDevice, which
essentially wraps the sensor HAL but adds two features to it:
- it keeps track of which sensors need to be activated
- it keeps track of what rate needs to be used
For this purpose an "identity" is associated with each real sensor
activation, so we can track them.
On start-up we check for gravity, linear-acceleration and
rotation-vector sensors, if they're not present in the HAL, we
synthetize them in sensor-service.
