90ed3e8d78 fix a few problems with BitTube
BitTube used to send objects one at a time and didn't
handle errors properly.

We now send all the objects in one call, which means they
have to be read as a single batch as well. This changes the
BitTube API.

Update SensorService to the new API.

Also added an API to set the size of the send buffer.

59abe7e090 Replace epoll() with poll() and rename PollLoop to Looper.
As part of this change, consolidated and cleaned up the Looper API so
that there are fewer distinctions between the NDK and non-NDK declarations
(no need for two callback types, etc.).

Removed the dependence on specific constants from sys/poll.h such as
POLLIN.  Instead looper.h defines events like LOOPER_EVENT_INPUT for
the events that it supports.  That should help make any future
under-the-hood implementation changes easier.

Fixed a couple of compiler warnings along the way.

a48bcf62b6 Added SensorManager.getMinDelay()
Exposed the new "min delay" sensor property through native and
java sensor apis. This allows the caller to know what is the
maximum rate at which a sensor can return events, or, if a sensor
works in "update" mode (events returned only when the value changes).

Also augmented SensorManager.regusterSensorEvent() so that it can
accept a value in microsecond in addition to the 4 constants already
defined.

a7352c9f4a new SensorService
remove old sensor service and implement SensorManager
on top of the new (native) SensorManger API.

589ce85ee4 first step at implementing the native sensor support
in this commit:
- implemented the C stub
- implemented the binder interfaces involved
- implemented most of the C++ client side

missing:
- SensorManager cannot connect to the SensorServer yet
(because there is no SensorServer yet)
