A recent change to optimize path rendering didn't account for
the destruction of native objects by the VM finalizer. We may be
done with the Java level version before we're done with the native
structure that's used by the display list. For example, a drawing
method on a View that creates a temporary path to render into the
canvas will implicitly create a native structure that is put onto
the GL display list. That temporary path may go away, but the native
version should stick around as long as the display list does.
The fix is to refcount the original native version of the path
and only delete it when the refcoutn reaches zero (which means that
it is no longer needed by any display list). This is a similar mechanism
used for bitmaps and shaders.

Modified default volume control logic in AudioService:
1 IN_CALL volume if in video/audio chat
2 NOTIFICATION if notification is playing or was playing less than 5s ago.
3 MUSIC
Modified silent mode:
- now also affect MUSIC stream type
- entering silent mode when VOL- hard key is pressed once while selected
stream volume is already at 0 (except for VOICE_CALL stream).
- exiting silent mode when pressing VOL+ hard key while in silent mode
Play sound FX (audible selections, keyboard clicks) at a fixed volume.
Modified audio framework:
- isStreamActive() method now implemented in AudioPolicyManagerBase (previously AudioFlinger)
- iStreamActive() now specifies a time window during which the stream is considered
active after it actually stopped.

It doesn't work (yet) for IPv6, but we can remove v4-centric notions from the framework.

Previously, display lists were used only if hardware acceleration
was enabled for an application (hardwareAccelerated=true) *and* if
setDrawingCacheEnabled(true) was called. This change makes the framework
use display lists for all views in an application if hardware acceleration
is enabled.
In addition, display list renderering has been optimized so that
any view's recreation of its own display list (which is necessary whenever
the visuals of that view change) will not cause any other display list
in its parent hierarchy to change. Instead, when there are any visual
changes in the hierarchy, only those views which need to have new
display list content will recreate their display lists.
This optimization works by caching display list references in each
parent display list (so the container of some child will refer to its
child's display list by a reference to the child's display list). Then when
a view needs to recreate its display list, it will do so inside the same
display list object. This will cause the content to get refreshed, but not
the reference to that content. Then when the view hierarchy is redrawn,
it will automatically pick up the new content from the old reference.
This optimization will not necessarily improve performance when applications
need to update the entire view hierarchy or redraw the entire screen, but it does
show significant improvements when redrawing only a portion of the screen,
especially when the regions that are not refreshed are complex and time-
consuming to redraw.

UsbManager:
- is now a service retrievable via Context.getSystemService(Context.USB_SERVICE).
- provides support for returning a list all connected USB devices
- broadcasts ACTION_USB_DEVICE_ATTACHED and USB_DEVICE_DETACHED when devices
are added and removed from the USB host bus
UsbDevice:
- represents an attached USB device.
UsbInterface:
- represents an interface on a USB device
- devices may have multiple interfaces if they provide multiple
sets of functionality (for example, android phones typically have interfaces
for both USB mass storage and adb)
UsbEndpoint:
- represents an endpoint on a USB interface
- endpoints are used for sending or receiving data
(only in one or the other direction)
UsbRequest:
- encapsulates a send or receive request to be sent over an endpoint

When someone referenced an empty string by putting in the special value
"@null" the string block was kept, but when filtering themes this wasn't
filtered because the framework thought it was actually a null string.

This enables the system bar to carve out a region through which
events will be sent to the IME behind it.
