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.

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.

External storage volumes that were emulated+encrypted needed to have
their encryption mapping removed so that it doesn't try to encrypt the
volume after formatting them.
This just wires through an argument through vold, and assumes that vold
will do the right thing even if there is no encryption mapping set.

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 allows us to properly reference count any globals (static or extern) that
need to potentially be cleaned up.

Added Surface.setPosition(float, float) which allows to set a surface's
position in float.

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).
