Accessibility focus is a token that can be put on any view and is
entirely controlled by accessibility services which decide whether
to put accessibility focus on a given view and what the traversal
strategy is.
Currently accessibility service use the view tree structure for
traversal which does not always reflect the logical order and the
user experience is sub-optimal. In such cases apps should be able
to influence how they are traversed for accessibility.
This change adds the notion of an accessibilty traversal order.
If a view has next in the traversal, an accessibility service has
to traverse the content of this view before traversing the content
next one.
This change will enable accessibility service to move away from
using the view tree and use spatial location of the content while
app developers can also influence the treversal order.

Existing hidden methods allow activities to be notified when their
windows have completed animating in. This change adds that capability
to system windows using a ViewTreeObserver callback since system
windows lack an activity token.
The first subsystem to use this is the UserSwitchingDialog which was
previously using a 250 msec timeout to dismiss the dialog. That
deadline was often missed leaving the user with no dialog on the
screen during the transition.
Fixes bug 16661752.

1. Add a command to NetworkManagementService to enable/disable
IPv6 ND offload via netd.
2. Make Nat464Xlat enable offload if clatd successfully comes up
on a wifi network (which means it detected a NAT64), and
correspondingly re-enable offload when the clatd interface
goes down.
This change does not enable clatd on wifi yet, that requires an
extra 2 lines to enable it.

Fixes no-op on method call after configuration change at the expense
of removing a micro-optimization that wasn't really needed.

These are available as XML attributes but were lacking setters. None
of the Window properties have getters, so just adding setters here.

If the kernel sends notification of an optimistic address then
treat is a useable address (isGlobalPreferred()).
Note that addresses flagged as IFA_F_OPTIMISTIC are
simultaneously flagged as IFA_F_TENTATIVE (when the tentative
state has cleared either DAD has succeeded or failed, and both
flags are cleared regardless).
Additionally: do not consider RFC 4193 ULA addresses sufficient
for "global preffered". They are, by definition, of global scope
but not sufficient for global reachability.
