Background:
In ag/406771 we stopped deleting empty stacks in activity manager
and window manager. This fixed a problem where dormant tasks were
being added back to stacks later.
In ag/476888 we introduced a callback to inform the ActivityView
holder that the embedded task was complete. This callback was made
from the new method ActivityContainer.onTaskListEmpty().
In ag/483035 onTaskListEmpty() was expanded to detach the stack of the
ActivityView and also removed the stack from window manager. There
was a mistake in that CL that causes it to remove any non-home stacks,
not just ones in ActivityViews.
That mistake left us with an empty stack in activity manager and no
corresponding stack in window manager. As a result, when trying to
bring back a task that used to be in this stack window manager threw
up an exception.
This fix limits the stacks detached by onTaskListEmpty() to those
on VirtualDisplays.
Fixes bug 17469145.

Previously, the input content to the color matrix computation was left
premultiplied. Since the color matrix could reduce the alpha channel,
the alpha was re-multiplied, but this was incomplete, and incorrect.
Instead, apply the color matrix in unpremultiplied space.

Remove token from deferred list of tokens to be removed once token
is removed. Leaving it in the list leads to logging messages like
"WindowManager: removeAppFromTaskLocked: token=AppWindowToken{...
} not found" when an attempt to remove it a second time fails.
Discovered in logs from b/17512377.

CTS tests cause the TaskPersister queue to fill faster than it can
drain. Since it contains screenshots this can consume massive
memory. Monkey may also cause the queue to back up.
Several optimizations are added to drain the queue when it gets
large:
- High water mark to recognize when queue gets too deep. Queue is
completely drained at this point so that obsolete files can be
removed from storage.
- Use Thread.yield() to give the TaskPersister write thread some cpu
cycles.
- Remove images from write queue when TaskRecord is removed from
recents.

When HDMI-CEC system audio mode is activated.
1. Hide volume bar when volume button is pressed in TV
2. Show volume bar when TV receives volume notification from
Audio Receiver.
Otherwise, (system audio mode off) follows normal TV's behavior.

Introduce a concept of a "root affinity" to a task -- this is the
affinity of the initial activity in the task. Use this instead of
the current affinity in findTaskLocked(), where we look for an
existing task to use for a NEW_TASK intent.
This changes the semantics of the new "relinquish task identity" mode
so that it doesn't relinquish the root affinity of the task. This
means when we are in the old style application-based recents matching
of findTaskLocked(), we will never count these tasks as the same as
the application's tasks only because they have relinquished their
identity to that application. This is probably okay, it is basically
putting a different line between new document-centric recents and
old application-centric recents when they are mixed together.
