On user-debug and eng builds, you can set the
"db.log.slow_query_threshold" system property to queries that
take longer than the specified number of milliseconds.
Set it to 0 to log all queries.
This property has been around for a while but it was implemented
poorly. In particular, it *changed* the behavior of the query
by calling getCount() while holding the Db connection.
In normal operation, the query will not actually run until later.
By putting the timing logic into fillWindow() instead, we ensure
that we only measure queries that actually ran. We also capture
cases where the cursor window gets filled multiple times.

Swiping the home screen causes the WindowManagerService to do
a bunch of work to keep the wallpapers in sync. First, it lays out
and places all windows. Also, it notifies the SystemUI process that
the wallpaper position has changed.
The layout/place operation is too much work - we only need to set
the position values for the wallpaper, not relayout the whole system.
The notification mechanism must exist, but should be optional. Most
wallpapers don't care (especially static ImageWallpapers). So we'll
give them a new API (WallpaperService.Engine.setWantsOffsets()) to
allow wallpapers to opt out of this process and avoid the performance
overhead.

1. AccessibilityInteractionConnection was non-static inner
class, hence keeping a handle to the enclosing ViewRootImpl
resulting in leaking activities.

A recent patch taking scroll into account was applied at the wrong
level. isVisible() expects positions that already take scroll into
account. isOffsetVisible() is where the initial bug was.
Cherry pick of 144415 from master.

Bug: 5520301
When an application requests a row from a SQLiteCursor that
is not in the window, instead of filling from the requested
row position onwards, fill from a little bit ahead of the
requested row position.
This fixes a problem with applications that seek backwards
in large cursor windows. Previously the application could
end up refilling the window every time it moved back
one position.
We try to fill about 1/3 before the requested position and
2/3 after which substantially improves scrolling responsiveness
when the list is bound to a data set that does not fit
entirely within one cursor window.

Fixed the documentation and comments for dips versus pixels.
Added a new DOUBLE_TAP_TOUCH_SLOP to replace the hard-coded and
*unscaled* value used in GestureDetector. Assuming this value was
ok for hdpi devices, set it to 20 / 1.5 ~= 16 in dips.
New method kept hidden to keep API unchanged.

Note that this will currently get rid of the Tethering option as
DUN tethering is broken, but that should get fixed shortly.
