If the destructor of SensorEventConnection gets called when the main
sendEvents loop of SensorService is executing it may result in a deadlock.
The loop promotes each connection to a strong_pointer, calls sendEvents
and cleans up the connection if necessary. It is possible that the sp's
destructor may delete SensorEventConnection which will call the dtor
~SensorEventConnection(). This dtor again needs SensorService mLock to
execute which may result in a deadlock.

This is used by media service to schedule video frames at the

i) Initialize sensor_event.flags to zero or wake_up flag before sending dropped flush_complete_events. This will avoid unnecessary acks.
Currently it is not set to anything which may result in garbage values for flags field.
ii) Change the dump format of SensorEventConnection.
iii) Add const to method signatures wherever applicable.

i) Significant Motion multiple clients fix. Make a copy of
mActiveConnections vector before cleaning up SensorEventConnections
when one-shot sensors trigger.
ii) Maintain a mapping between flush_complete_events and
SensorEventConnections to accurately map flush() API calls and
corresponding flush_complete_events
iii) Remove all references to 1_1 and 1_2 HALs.
iv) Dynamically allocate sensor_event buffers in SensorService main
threadLoop.

i) Fix a possible race condition when adding a pending flush connection
to mActiveSensors data structure.
ii) Invalidate flush_complete_events as soon as they are consumed by a
connection so that they are not used by other connections which are
registered for the same sensor.

This makes it possible to tell whether two HW vsync signals are too
far apart because one was late, or because we turned HW vsync off
briefly between them.

1) Limit maxEventsToWrite depending on the size of the socket
buffer allocated (Fix for write failure on manta).
2) Do not call flush() if the sensor is not activated (OEM issue).

Display configs for external displays are stored in the framework
everytime we receive a hot plug to connect. However, since the
configs are not cleared on disconnect, framework will just assume
that the configs are valid. This does not work for use cases when
you connect/disconnect external displays with different resolutions.
e.g. 1080p to 4K and vice-versa
With this change we clear the display configs and repopulate when
we receive a hot plug to connect.

By not committing the results of composition for empty frames, we
avoid spitting out series of black frames for virtual displays that
don't have visible layers. We still draw one black frame when going
from having layers to not having any. In particular, this avoids
having a series of empty frames due to re-compositing the primary
display in the period between creating the virtual display and adding
layers to it.

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.

Modify SurfaceFlinger to use VirtualDisplaySurface in all cases when a virtual
display is used. Add functionality in VirtualDisplaySurface to resize the
buffers aquired in the QueueBufferOutput. Add transaction support in
SurfaceFlinger for resize. Add the modification of the size in DisplayDevice.
