Bug: 5335420
Fixed a bug in VelocityTracker where the output velocity was
not being set to zero when not available.
Added a condition to ensure that the velocity is at least
the minimum fling velocity before continuing. If not, then
the user is trying to stop the fling and scroll more precisely.

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: 5265529
Calculate the velocity using the most recent touch sample as the
point of reference instead of the oldest. This change more heavily
weights recent touch samples and reduces the sample time window
used for calculation. This significantly improves the accuracy
of fling gesture detection.

Updated the command name lists, and masked off the additional bits in
the command word when doing the name lookup.
Made descriptor values easier to grep for and consistent with kernel
output (i.e. decimal rather than hex). Attempt to show transaction
descriptors as such (they're in a union with a pointer).
Also, the writeLines() function in Static was using a no-op
logging call to write an iovec. It looks like all callers are using
N=1, so I just added a log for the first string.

In queuebuffer, if the surfacetexture returns an error,
surfacetextureclient should check for that and pass on the error.

this bug was introduced recently. in some situations Surface::lock()
is not able to preserve the content of the back buffer and needs
to tell the caller to redraw everything.

This change fixes the NATIVE_WINDOW_QUEUES_TO_WINDOW_COMPOSER query of
Surface and SurfaceTextureClient. Surface now uses the inherited
SurfaceTextureClient implementation of this query. SurfaceTextureClient
now queries SurfaceFlinger to determine whether buffers that are queued
to its ISurfaceTexture will be sent to SurfaceFlinger (as opposed to
some other process).

we were not reseting mCurrentTexture in some situations
which in turn caused dequeueBuffers() return a
"FREE" buffer that was also current.
Very often it was harmless, but it created a race with
updateTexImage() which could cause the following
queueBuffers() to fail.

we would leak a weakref_impl if a RefBase was never incWeak()'ed.
there was also a dangling pointer that would cause memory corruption
and double-delete when a custom destroyer was used to delay the
execution of ~RefBase.
it turns out that the custom destroyer feature caused most of the
problems, so it's now gone. The only client was SurfaceFlinger
who now handles things on its own.
RefBase is essentially back its "gingerbread" state, but the
code was slightly cleaned-up.

we now make sure to drain the buffer queue on disconnect.
this happens only when in synchrnous mode. in async mode
we clear all buffers except the head of the queue.
for extra safety we also catch the null pointer
in updateTexImage (which should never happen) and return
an error.

This fixes an issue where the Surface readFromParcel code was leaving
unread parcel data in the case where the Surface was re-used from the
sCachedSurfaces cache. On a cache miss the code is creating a new
Surface from the remainder of the parcel data. On a hit that data was
being left unread, so anything that parcels a Surface followed by
additional arguments may end up reading the wrong values.

the first time a surface was connected, the values returned
by query NATIVE_WINDOW_DEFAULT_{WIDTH|HEIGHT} and
NATIVE_WINDOW_TRANSFORM_HINT were wrong until a call

Bug: 5064702
Introduced the concept of an InputListener to further decouple
the InputReader from the InputDispatcher. The InputListener
exposes just the minimum interface that the InputReader needs
to communicate with the outside world. The InputReader
passes arguments to the InputListener by reference, which makes
it easy to queue them up.
Consolidated all of the InputReader locks into one simple global
Mutex. The reason this wasn't done before was due to potential
re-entrance in outbound calls to the InputDispatcher. To fix this,
the InputReader now queues up all of the events it wants to send
using a QueuedInputListener, then flushes them outside of the
critical section after all of the event processing is finished.
Removing all of the InputMapper locks greatly simplifies the
implementation.
Added tests for new stylus features such as buttons, tool types,
and hovering.
Added some helpers to BitSet32 to handle common code patterns
like finding the first marked bit and clearing it.
Fixed a bug in VelocityTracker where the wrong pointer trace
could get cleared when handling ACTION_POINTER_DOWN. Oops.
Changed PointerCoords so it no longer stores useless zero
axis values. Removed editAxisValue because it is not very
useful when all zero value axes are absent and therefore
cannot be edited in place.
Added dispatch of stylus hover events.
Added support for distance and tool types.

This change relaxes an error check in SurfaceTexture::setBufferCount to
allow clients to explicitly set a buffer count of 2. The clients that
will do this are camera and video decode. Previously it was thought
that for those clients we would always use async mode, which requires a
minimum of 3 buffers. However, we now believe that for some devices it
may make sense to use synchronous mode (with 2 buffers) to reduce memory
usage.

all-subdir-makefiles can be used only before any "include" statement.

The built-in ZipFile class was quite a long time to find an unpack
libraries. Move everything to using the libutils ZipFileRO class that
goes quite a bit faster. Initial measurements are 6 times faster than
the Java code.
Also, read files off the disk and compare their CRC against the APK's
CRC to see if we need to write the new file to disk. This also cuts down
the bootup time by up to a second per APK that has native files.

The Surface is already using SurfaceTexture internally and it is parcelable. This
is intended to replace and phase out ParcelSurfaceTexture in favor of creating a
new Surface.java object from an existing SurfaceTexture.
