1. Now when an interrogating client requires an AccessibilibtyNodeInfo
we aggressively prefetch all the predecessors of that node and its
descendants. The number of fetched nodes in one call is limited to
keep the APIs responsive. The prefetched nodes infos are cached in
the client process. The node info cache is invalidated partially or
completely based on the fired accessibility events. For example,
TYPE_WINDOW_STATE_CHANGED event clears the cache while
TYPE_VIEW_FOCUSED removed the focused node from the cache, etc.
Note that the cache is only for the currently active window.
The ViewRootImple also keeps track of only the ids of the node
infos it has sent to each querying process to avoid duplicating
work. Usually only one process will query the screen content
but we support the general case. Also all the caches are
automatically invalidated so not additional bookkeeping is
required. This simple strategy leads to 10X improving the
speed of the querying APIs.
2. The Monkey and UI test automation framework were registering a
raw event listener for accessibility events and hence perform
connection and cache management in similar way to an AccessibilityService.
This is fragile and requires the implementer to know internal framework
stuff. Now the functionality required by the Monkey and the UI automation
is encapsulated in a new UiTestAutomationBridge class. To enable this
was requited some refactoring of AccessibilityService.
3. Removed the *doSomethiong*InActiveWindow methods from the
AccessibilityInteractionClient and the AccessibilityInteractionConnection.
The function of these methods is implemented by the not *InActiveWindow
version while passing appropriate constants.
4. Updated the internal window Querying tests to use the new
UiTestAutomationBridge.
5. If the ViewRootImple was not initialized the querying APIs of
the IAccessibilityInteractionConnection implementation were
returning immediately without calling the callback with null.
This was causing the client side to wait until it times out. Now
the client is notified as soon as the call fails.
6. Added a check to guarantee that Views with AccessibilityNodeProvider
do not have children.

This is between the two previous attempts. I returned the part from the
original that was breaking gallery, but have some new code to detect when
something about the window params has changed that would require a
layout pass to make sure we still do a layout then, even if the window is
not currently visible.

When an AudioTrack is in underrun state, the AudioFlinger mixer will
sleep for a short period of time to give the app a chance to fill the
AudioTrack buffer. If the AudioTrack is still not ready during next mixing round,
the mixer will proceed with other tracks.
If an application keeps a steady underrun condition, the AudioFlinger mixer will
alternate between ready and not ready states. In the longer term this will cause the
audio HAL to underrun.
There is a mechanism to reduce the sleep period if the mixer is not ready several times in a
row but this mechanism is defeated by the alternating ready/not ready conditions.
The fix consists in only increasing sleep time if the mixer is ready for at least two
consecutive times.
Issue 5904527.

Bug introduced in recent refactoring

Do not move cursor when selectAllOnFocus and focus just happened.
The didTouchFocusSelect() condition was not copied over from ArrowKeyMM.

It seems that something (probably layout transitions)
occasionally leaves the navigation bar layout in a weird
state such that most of the buttons are offscreen. For
example, the portrait nav bar might have buttons with widths
matching the nav bar's old width from landscape; the
clickable regions will therefore be far off the right edge
of the display.
The navigation bar now looks for this situation when the
size of the view changes and corrects for it.

This was a bug only when the status bar was hidden, the screen space for
the nav bar would not be correctly removed for all frames used in layout
computation.
This code really $*#&^!! needs to be cleaned up, the whole "status bar
is the system bar when on a tablet so it should take space from apps,
but status bar doesn't do that on phones but on phones there is a nav
bar that does the same thing" thing is whacked.
Proof that evolution DOESN'T WORK!!!!!!!!!!

Added a new method ContentObserver.onChange(boolean, Uri) that
receives the changed content Uri. This can help applications make
better decisions about how to interpret a change notification.

- was a subtle regression introduced when fixing bug #5753006
- as we are now using SkPaint::kGlyphID_TextEncoding (glyph encoding)
instead of SkPaint::kUTF16_TextEncoding (UTF16 encoding), we need to
force the UTF16 encoding in some cases that are NOT going thru
the TextLayoutCache / Harfbuzz shaping
- fix also breakText() the same way
- also clean some old comment
- Warning: depends also on a CL from Skia for having getBaseGlyphCount() "const"

Improved the documentation a little bit.
Fixed a bug in ContentService wherein if a ContentObserver was
passed as an argument and its deliverSelfNotifications() method
returned true, then notifyChange would tell all observers that
the change was a self-change even though it was only a self-change
from the perspective of the provided observer.
Deprecated ContentObservable.notifyChange since it is never
used and in general it shouldn't be because we want the notification
to be posted to the handler.

We now have an animation that can start as soon as we detect to
rotate the screen, and have a different phase once the new UI
is ready to complete the transition into it.

In change Ief74d0e4f4f28dff7a435e9dab1fab1ca1d9bfaf with a sha1 of
e81932e92a773538e1ad1ad1d4bfd8f241860c8d it seemed like a good idea
to throw away all TLV's on errors. In retrospect that was probably
not a good idea. For example on the MTN Ghana SIM the error
occurs because of some 0 pad bytes at the end, all of the actual
TLV's are good, so throwing away everything is unreasonable. Instead
accepting what is valid seems a better approach.
Also, add a couple debug lines on error paths.

This fixes a complaint from carriers (that we used 8.8.8.8), but also
fixes the case where there is only room for one live radio
connection: the secondary connection (tethering) doesn't have a
default route to prevent on-device traffic from slipping out on the
tethering connection, but tethered dns is proxied through dnsmasq, so
it is appearing as on-device traffic and is unroutable. By switching
to the carrier-indicated dns servers we can use the host-routes
already set for those and kill two bugs with one fix.
