DO NOT MERGE: Sensor multi HAL
Squashed commit of:
Move sensors multi HAL to libhardware
Added a SensorEventQueue, a circular buffer meant for reading with one thread
and polling a subhal with another. The writing thread gets access to pointers
in the internal buffer. This design avoids a memcpy on write when the multihal
fetches subhal events using poll().
Unit-tests include multithreaded reading and writing lots of events, in
random-sized chunks.
This is not used by the multihal yet. That will be a different CL.
MultiHal multithreaded polling
Tests SensorEventQueue I/O when the queue is full.
Reduced debug logging in multihal.
deactivated multihal logspam, made warnings warnings, left critical startup info
Removed unneeded linux/input.h includes, to fix Mac SDK build
