A Dream is an activity that is launched by the window
manager after a specified idle time. You might think of this
as a "screen saver", but with the same capacity for
interactivity as any other application.
The window manager maintains a timer (like the screen lock
timer) that is reset on userActivity; the timer is suspended
during wakelocks and when the screen is off.
When the timer elapses, the user's preferred dream module is
launched (by reading Settings.Secure.DREAM_COMPONENT, which
is configured through the Settings app UI).
Like a dock app, the user can install new dreams and a
single application package may contain multiple dream
activities. Unlike the dock mode, however, there is no
"screensaver mode" for the system to manage. This allows us
to offer the user the ability to run a dream at any time, in
addition to making the overall mechanism quite simple.
There is no public API for this facility.
There is, however, a useful/recommended base class for dream
activities in the support library (change I4559a958).

If a view is not accelerated but has its layer type set to
LAYER_TYPE_HARDWARE, then the framework will use the old drawing cache
approach, to cache it in a bitmap. This works fine, but when the layer
is set to NONE, that drawing cache is not destroyed, as it would be were
the layer set to LAYER_TYPE_SOFTWARE. This prevents future invalidations on
the view from working correctly because the bitmap cache has never been
destroyed and recreated.
The fix is to always destroy the drawing cache when the layer type is
changed from SOFTWARE or HARDWARE, to make sure that it gets set appropriately
regardless of the state of the view's acceleration.

* commit '1d340a3c24913d8750900355cd92ef5742eea11f':
DO NOT MERGE. From main -- Start work on simulating landscape/portrait when orientation is locked.
* commit '0eac092766d7871b34927442ee0b6e27e7e1317b':
DO NOT MERGE. From main -- Start work on simulating landscape/portrait when orientation is locked.
Not yet working, so turned off.
Also fix a bug where the display size configuration became inconsistent
after a configuration change -- we now figure out everything about the
display size when computing a new configuration.

Applications now get the display size from the window manager. No
behavior should be changed yet, this is just prep for some real
changes.

Replace config_emulateExternalStorage, config_externalStorageRemovable,
config_externalStoragePaths, config_externalStorageDescriptions and
config_mtpReserveSpaceMegabytes resources with an XML resource file
to describe the external storages that are available.
Add android.os.storage.StorageVolume class
StorageManager.getVolumeList() now returns an array of StorageVolume

Activity manager now does all dump requests into apps
asynchronously, so it can nicely timeout if there is an
app problem. Also lots of general cleanup of the am
dump output.

Introduces public API to apply "tags" to track data traffic originating
from the current thread. (Under the hood, the tags are maintained and
applied in BlockGuard.) Also adds tag/untag methods for developers who
maintain their own Socket pools.
