An earlier fix nooop'd invalidate calls on non-visible views. This
caused an issue where changes to the view while it was not visible
(such as changing the text of a TextView) would not get picked up
by the invalidation process.
The fix is to automatically invalidate() a view when it becomes
visible, to account for any changes that may have occurred to its
content while it was not visible.

It looks like this is caused by the change in HC to stop activities when
the screen is off. ViewRootImpl (a.k.a. ViewRoot) has special code to
avoid doing work when it is stopped, and it is now stopped when the screen
is off. The problem here is if the window's activity is stopped when the
window is first displayed, then it would never do the initial fitSystemWindows()
with the status bar offsets given by the window manager, and never do this
again until the status bar changes.
Also included here is some re-arranging of the code dealing with the offsets
changing, because it was dealt with in two places and only one had a bunch of
code dealing with HW accelerated drawing and performing the fade transition
between states. Now all of that is unified into one place.

...(when turning display on after recently turning it off)
Also clean up when we decide to turn the screen on to improve that
transition. There are still problems here with turning it on
before the wallpaper gets dispayed.

There was a bug in the invalidation code that prevented some
animations fropm starting. An INVISIBLE view would mark some dirty
flags then propagate the invaliation up the parent hierarchy. This would
cause a redraw of the hierarchy, but would not include the invisible
view (invisible children do not get drawn). Thus the flags wouldn't get cleared.
Later, an animation to fade the view in (making it VISIBLE on start) would
be started on the view. But the invalidation triggered by that animation would
not propagate because the invisible view would see that it was already
invalidated, and wouldn't send the message along. No invalidation means no drawing,
so the animation wouldn't start because the invalidation didn't make it's way up to the
top and the child's parent did not redraw.
The fix is to noop the invalidate() call for GONE/INVISIBLE views which do not
have animations set on them. Making these views VISIBLE later will trigger
an invalidation, as will starting an animation on them, so the behavior should
not change except for the buggy situation.

This introduces a new facility for code during the boot process
to display messages to the user through a progress dialog. This
is only for use when performing longer-than-usual post-upgrade
operations such as running dexopt on applications or upgrading
databases.

- Sometimes, the applyUpdate was applied through draw() and the
underlying matrix was not updated in time, causing "jitter". Add a
matrix update call in draw().
- Switch to invalidateParentIfNeeded() in setTransform().

Bug: 5049148
Finished stylus support, including support for indirect stylus
and mouse tools.
Added TILT axis. When stylus tilt X/Y is available, it is transformed
into an orientation and tilt inclination which is a more convenient
representation and a simpler extension to the exiting API.
Touch devices now only report touch data using a single input
source. Previously touch devices in pointer mode would report
both absolute touch pad data and cooked pointer gestures.
Now we just pick one. The touch device switches modes as needed
when the focused application enables/disables pointer gestures.
This change greatly simplifies the code and reduces the load
on the input dispatcher.
Fixed an incorrect assumption that the value of ABS_(MT_)DISTANCE
would be zero whenever the stylus was in direct contact. It appears
that the correct way to determine whether the stylus is in direct
contact (rather than hovering) is by checking for a non-zero
reported pressure.
Added code to read the initial state of tool buttons and axis values
when the input devices are initialized or reset. This fixes
problems where the input mapper state might have the wrong initial
state.
Moved responsibility for cancelling pending inputs (keys down,
touches, etc.) to the InputDispatcher by sending it a device reset
notification. This frees the InputReader from having to synthesize
events during reset, which was cumbersome and somewhat brittle
to begin with.
Consolidated more of the common accumulator logic from
SingleTouchInputMapper and MultiTouchInputMapper into
TouchInputMapper.
Improved the PointerLocation output.

This will save apps the trouble of having to first remove
the lights-out or hide-navigation flags before reapplying
them (in situations where the system UI has decided to
override those flags).

This change fixes some problems when the view hierarchy contains
duplicate ids, such as when ListViews contain nested custom views.
If the custom views contain next focused id hints, then the system
should prefer the other views within the ListView item over any
other views outside of the ListView item.

SeekBar widgets were not good citizens when placed in scrolling containers.
Detect when a SeekBar being touched is in a scrolling container and fall
back to a touch slop-based method for beginning a drag. Taps along the
seek bar itself will still change the value on touch up, even if the touch
slop never initiated a proper drag.
Factor out the code used to determine scrolling container status in View
into something that can be reused elsewhere in the framework; leave it
@hidden for now.
