Bug: 5332296
NewStringUTF expects modified UTF-8, so it barfs on UTF-8 strings
that contain high codepoints. Even though it results in an extra
copy being performed, first convert to UTF-16, then call NewString.

Bug: 5332296
Removed dead code in SQLiteCursor related to the use of a background
query thread. This code could result in CursorWindows being modified
concurrently or used after free. This code is broken, unused and
is just in the way.
Added comments to explain how CursorWindow ownership is
supposed to work for AbstractWindowedCursors. (There are still cases
where cursor windows get dropped on the floor without being closed.
Those will be taken care of in a subsequent patch.)
Cleaned up SQLiteQuery.fillWindow to eliminate duplicate code and
remove bits that were only needed for background loading, like
returning -1.

Bug: 5430009
Some CTS tests try to call getType on fields in empty
cursor windows or with out of bound column indices (-1).
Restoring the previous behavior of returning FIELD_TYPE_NULL
instead of throwing. Fix this later.

- welcome back start / count
- goodbye log clusters
- clean Paint code
- make private some functions as they should be
- improve memory allocation (create only one Shaper and reuse it for for shaping the runs in
the same input text)

The code is functionally equivalent, but a little more efficient
and much easier to maintain.

- the gain is about 5% and the timing is more stable
- use compare_type() and strictly_order_type()

It's not okay to pass null to JNI methods and trust that it will just
back off and return a null result cleanly. Fixes bug 5361822 .

- makes TextLayoutCache not carring about start/count. Basically he will cache the result for
the full string and gives back the "chunk" corresponding to start/count
- changed the TextLayoutCacheValue API to take start/count parameters
- add Harfbuzz LogClusters in TextLayoutCacheValue as it is needed for extracting the start/count "chunk"

mManualBufferMode is only for CAMERA_MSG_PREVIEW_FRAME. If it is

Bug: 5265529
Rewrote the velocity tracker to fit a polynomial curve
to pointer movements using least squares linear regression.
The velocity is simply the first derivative of this polynomial.
Clients can also obtain an Estimator that describes the
complete terms of the estimating polynomial including
the coefficient of determination which provides a measure
of the quality of the fit (confidence).
Enhanced PointerLocation to display the movement curve predicted
by the estimator in addition to the velocity vector.
By default, the algorithm computes a 2nd degree (quadratic)
polynomial based on a 100ms recent history horizon.

Bug: 5156144
Input channels could leak or simply live longer than they should
in some cases.
1. Monitor channels (used by the pointer location overlay) are never
unregistered, so they would leak.
Added code to handle failures in the receive callback by closing
the input channel.
2. The DragState held onto its input window and application handles
even after the input channel was disposed.
Added code to null these handles out when they are no longer needed.
3. Input channels previously used as input event targets would stick
around until the targets were cleared (usually on the next
event).
Added code to detect when the input dispatcher is in
an idle state and to proactively clear the targets then
to ensure that resources are released promptly.
4. Native input window handles held onto the input channel even
after the input window was removed from the input dispatcher.
Consequently, the input channel would not be disposed until
the input window handle itself was freed. Since the input
window handle is held from managed code, this meant that the
window's input channel could stick around until the next GC.
Refactored the input window handle to separate the properties
(info) and identify (handle) state into different objects.
Then modified the dispatcher to release the properties (info)
when no longer needed, including the input channel.
7. The pointer location overlay does not actually use its
standard input channel, only the monitor input channel.
Added INPUT_FEATURE_NO_INPUT_CHANNEL to allow windows to
request that they not be provided with an input channel
at all.
Improved some of the error handling logic to emit the status
code as part of the exception message.
