Instead of calling setLeft(), setTop(), setRight(), setBottom()
separately, make one call that does all at the same time.

For now, only animators use it but we can consider migrating
drawable cache to it as well.

In explore by touch mode the user performs a double tap to click on
an item. In this case the system sends down and up events at the
location of accessibility focus. The accessibility focused view may
be partially covered. In order to click in this view we compute a
point where to send the down and up events. This clicking strategy
is a bridge-gap and we will switch to accessibility actions in the
future.
When computing the point to click we were taking into account whether
the view was covered by a clickable sibling or a clickable sibling of
a predecessor. Despite our expectation cases in which this is not
enough happen in practice. In particular, the focused view may be
covered by a clickable descendant of a non-clickable sibling of a
predecessor that covers the focused view. This change takes care
of handling this case. Note that computing the click point is a fair
amount of work but this happens very rarely and on demand. Also the
code is short circuiting where possible.

An accessibility service may register to observe the interactive windows
on the primary display. These windows are the one that has input focus and
ones a sighted user can touch. It is sometimes beneficial for an
accessibility service to overlay a window to intercept user interaction
and based on that introspect and perform an action on the windows that
are on the screen. This is problematic as overlaying a full screen window
that is touchable prevents the accessibility service to introspect the
content under this window.
This change adds a special type of window that only an accessibility service
can place which does not affect what an accessibility service can "see" on
the screen. Hence, even putting such a window full screen the service will
be able to interact with the other interactive windows it covers.

The Lollipop release introduced a feature that allowed
apps to extend under the navigation bar. This also means
any popup window that is anchored to the bottom of its
parent window will overlap with the navigation bar if the
parent window is extending underneath the navigation bar.
This change introduces a new window flag
(FLAG_LAYOUT_ATTACHED_IN_DECOR) that allows the app to
specify if the popup window should be attached to the decor
frame of the parent window thereby avoiding an overlap
with the screen decorations.
By default the flag is set on SDK version LOLLIPOP_MR1 or
greater and cleared on lesser SDK versions.
Also, replaced flags FLAG_NEEDS_MENU_KEY and
PRIVATE_FLAG_NEEDS_MENU_KEY_SET with needsMenuKey state
variable to make room for the new
FLAG_LAYOUT_ATTACHED_IN_DECOR flag.
