SurfaceControl.
In a recent CL we introduced a call to Surface#createFrom, in order to
recreate the Surface object from the underlying SurfaceControl, as a
workaround to emulate when it was parcelled over binder in the past.
However this is causing BufferQueue abandoned errors when stopping and
resuming some applications. To understand them, we need to revisit the
SurfaceView destruction process when handling onStop.
First mWindowStopped will be set to true (SurfaceView#windowStopped),
and we should then enter updateSurface. Our requested visibility will
now be false and so we emit the Surface destroyed callbacks. Notice in
the finally block in mUpdateSurface, we will release mSurface, but we
will NOT null mSurfaceControl. Inline documentation explains why.
In the case that the activity is not actually being destroyed, it's
possible that we may not get a dispatchDetachedFromWindow. This means
that we will not null mSurfaceControl. Now if the activity is
un-stopped and we re-enter updateSurface we encounter a problem
state. "creating" will be set to false since mSurfaceControl != null,
however mSurfaceControl will not point to a valid surface.
Prior to the introduction of the #createFrom call, this unwanted state
didn't cause any problems. Because mSurface was released back in the
finally block as we were stopping we now fall out of the
mSurface.isValid() block in updateSurface. As we reach the finally
block again, we would now set mSurfaceControl=null since the app was
no longer stopped. Later when we reach updateSurface again (which
tends to happen quite often) it will now be null and we will correctly
set creating=true, create a valid SurfaceControl, and move along
happily. However following, the introduction of this
Surface#createFrom call we will now reinitialize the Surface from an
invalid underlying SurfaceControl. This means we will enter the
mSurface.isValid block, but will proceed to emit an invalid Surface to
the client in the callbacks.
We avoid this state by making creating=true even if
SurfaceControl=non-null when the calculated visibility changes from
invisible to visible.

There is an issue (seemingly preexisting) with getPositionInWindow
after toggling view visibility. We see it when showing a view,
hiding it, and then showing it again. At this point we end up
with this call-stack:
SurfaceView#setVisibility->SurfaceView#updateSurface
->View#getPositionInWindow
and getPositionInWindow fills in the wrong values. This newly discovered
bug is tracked as 62839113.
In a second bug, introduced in the SurfaceView refactoring,
we are not appropriately clearing the last RenderThread reported
position when toggling visibility. This means that even after the
setVisibility call when getPositionInWindow begins returning
the correct values, we don't update the position. This CL fixes
that and fixes 62653411 as a result. However we still have a flicker
as we did in N as the initial position is wrong.

There are some apps that use the Surface object itself to indicate
changes. As a result, recycling the existing Surface object for

Currently if View.setTooltipText is called while
the tooltip is being shown for that view, it will
update the displayed text. The tooltip then will
resize to wrap around the new text, but not change
its position. This looks confusing if the new text
is significantly shorter or longer.
Removing this functionality until proper
re-positioning is implemented.

Let's first understand how mView could become null. Notice
at the beginning of performTraversals, there is a check that
mView != null, and so it is nulled while we are in the function.
mView is package private and there are only two places which assign
to it, ViewRootImpl#setView and ViewRootImpl#doDie. setView is guarded
by mView == null. But mView was not null (per the check at the beginning
of performTraversals) and so mView is being nulled by doDie().
doDie() only has 3 callpoints:
1. ViewRootImpl#die(). Here though, calling it is guarded by
!mIsInTraversal. !mIsInTraversal is unconditionally set at the
beginning of performTraversals, and so this isn't our caller.
2. ViewRootHandler, handling MSG_DIE. This runs on the same thread
as performTraversal, and so it can't be our nuller.
3. WindowManagerGlobal#addView. This must be our nuller.
We see WindowManagerGlobal#addView will call doDie in the case that
we attempt to add a view which we had previously set to be removed
but deferred removal of. Now we can construct a reasonable sequence
for getting here:
1. requestLayout(). Perform traversals ends up on handler.
2. removeView(). MSG_DIE ends up on handler, View ends up in mDyingViews
3. performTraversals is executed by the handler
4. From a callback initiated by performTraversals (e.g. measure)
the client calls WindowManagerGlobal#addView on the view which
was just removed.
5. We are still in performTraversals so MSG_DIE hasn't been processed
yet. This means that WindowManagerGlobal will perform the doDie
immediately nulling mView.
6. We return to performTraversals and crash.
We can see shortly after the offending call to doDie, a new ViewRoot will be
constructed and so whatever traversal we are doing on the old one doesn't
seem particularly important. It doesn't seem that we can do any better
than letting it fall through without crashing.

Previously, it was possible for the view hierarchy to be measured,
laid out, and drawn around a window frame size that did not match
the current configuration. This stems from new configurations not
always propagating back from WindowSession#relayout, which is
called from ViewRootImpl.
This changelist makes WindowManagerService#relayoutWindow always
return the latest configuration. It also adds rotation to the
configuration.

Most @SystemApi methods should be protected with system (or higher)
permissions, so annotate common methods with @RequiresPermission to
make automatic verification easier.
Verification is really only relevant when calling into system
services (where permissions checking can happen on the other side of
a Binder call), so annotate managers with the new @SystemService
annotation, which is now automatically documented.
This is purely a docs change; no logic changes are being made.
