VelocityTracker was implicitly assuming that the pointer ids in
a MotionEvent were ordered. That is not necessarily the case
so we need to be careful while copying the pointer coordinates out.

Fixed a few bugs related to the id-to-index mapping for
pointer coordinates.
Tightened the bounds on the resampling time interval to
avoid predicting too far into the future.
Only lerp X and Y components of motion events.
Alter the future to satisfy past predictions. (Rewrite touch
events to conceal obvious discontinuities.)
Added a system property to control whether resampling is enabled
for debugging purposes.

Bug #6408362
FontRenderer allocates large font textures when more room is needed
to store all the glyphs used by an application. Thse large textures
are the first to be freed when memory needs to be reclaimed by the
system. When freeing a texture, the renderer would however not set
the texture name to an invalid name, leading future allocations to
be performed on the same texture name. That name could have by then
be recycled by the driver and returned by a call to glGenTexture
and used to create an entirely different texture. This would cause
the font renderer to point to the wrong texture, thus leading to
the "corruptions."

Some logic in the native matrix code would determine that a matrix was
'pureTranslate' based on the scale values of a matrix being close-enough to 1,
which was within a very small epsilon. This works in general, because screen space
coordinates make that epsilon value irrelevant, so close-enough really is close-enough.
However, TextView, when centering text, works in a coordinate system that is quite
huge, with left/right values about 500,000. These numbers multiplied times that small
epsilon value would give a result that was significant, and would cause a miscalculation
of up to 4-5 pixels, causing the snap that we'd see for a couple of frames as the
scale got "close enough" to 1.
The fix is to remove the optimization of "close enough". What we really need the matrix to
do is to identify itself as being translate-only when no scale as been set (which is the
default). For the purposes of that check, it is good enough to simply check the values against
1 directly. Similarly, the bounds-check logic needs to check against 0 and 1 directly.

An optimization for paths is to only create a texture for the original native
Path object, and have all copies of that object use that texture. This works in
most cases, but sometimes that original path object may get destroyed (when the
SDK path object is finalized) while we are still referencing and using that object
in the DisplayList code. This causes undefined errors such as crashes and hanging
as we iterate through the operations of a destroyed (and garbage-filled) path object.
The fix is to use the existing ResourceCache to refcount the original path until
we are done with it.

The window manager policy made some incorrect assumptions about the
meaning of the Configuration.keyboard field. We need to be more
careful about distinguishing between built-in and external keyboards.
Most of this change is to move the determination of the parts of
the Configuration related to input devices into the WindowManagerService
leveraging new features of the InputManagerService to good effect.
Then we plumb through the flag that indicates whether a device
is internal or external so that we can be more particular about
how the lid switch effects changes to the Configuration.

There was a bug in the DisplayList code for layers where we would
set the alpha value for a layer only if the alpha were non-1. This works
most of the time (since the value is usually 1 and doesn't need to
be set at all, and if the value is non-1, it is set correctly). But when
the value has been set to a non-1 value, setting alpha back to 1 cannot happen
due to this logic. This caused launcher to have some invisible pages when
returning to Home because those pages previously had an alpha value of 0, and
setting the alpha to 1 had no effect due to this DisplayList code.
The fix is to simply remove the check for non-1 values; we should
always set the alpha value of layers to handle all cases.

Bug #6365056
WebView enqueues a functor in the hardware renderer to handle
animations and this functor is called at a later time by the
hardware renderer. However, the functor was not removed from
the queue when WebView was removed from the window. This could
cause the hardware renderer to attempt to execute an invalid
functor and lead to a crash.

Changed the English US keymaps to implement a strict US key map
with no additional ALT functions.
Fixed a bug copying the alias in the InputDevice copy constructor.
Added support for end of line comments in KCM and KL files.
