DisplayList properties are still disabled default (flags in View.java
and DisplayListRenderer.h). When they are enabled, and when a View has
a DisplayList, invalidations due to property changes are now optimized
to avoid causing DisplayList recreation. This eliminates the drawing step
of invalidation (due to changes in these properties), only requiring
issuing the previously-created DisplayList to the GL renderer. Invalidation
is slightly faster (less overhead as we walk up the hierarchy), getDisplayList()
is potentially much faster (going down to ~0ms), depending on the complexity
of the View being redrawn and the size of the invalidated hierarchy.

Make the database opening code more robust in the case of
read-only database connections.
Check whether a PRAGMA needs to be issues before doing it.
Mostly it's harmless but it can grab a transaction on the
database unnecessarily.

Bug 5763685
Long text in a ScrollView (not when the View's internal
scroll is used) is cached as a unique display list when hardware
rendering is on.
As a result, each time the text is edited, the entire display
list has to be updated, which takes a significant amount of
time (up to 500ms for a few thousand lines), proportional to the
size of the text.
This CL splits the text into multiple display lists as the
text is edited. The boundaries of the display list are aligned
with paragraphs.
There is still an issue when the number of lines changes: onLayout()
is called which invalidates all the display list. When the source
of that change is line wrapping and not a change in the view's
dimensions, we should be able to simply shift down the previous DL
instead of re-creating everything.

A recent change to enable View properties at the native DisplayList level
mistakenly cuased Animation transforms get be ignored for any View with
a DisplayList. The correct code should have checked whether DL properties
were enabled for the view (disabled by default for now).

The purpose is to let face unlock always get the camera
successfully. What happened was the camera applications may
have opened the camera in onResume under the lock screen.
This API lets face unlock take the camera from the camera
application. A new permission will be added, so other
applicatoins won't be able to take the camera from the face
unlock.

If the remote end of a bulk cursor died, then it was possible
for getColumnNames() to return null, violating the invariant
that it never returns null. As a result, the application could
crash in strange ways due to an NPE.
Since we are often interested in the column names anyhow, prefetch
them when setting up the bulk cursor adaptor. This way, a
remote cursor will never return null even if the remote end died.
It is possible for an application to continue to use a remote cursor
even after the provider has died unless it needs to requery it
for some reason. Of course at that point, bad things will
happen... but usually the app is better prepared for it than
if it just randomly encounters a null array of column names.
This change also optimizes the bulk cursor adaptor to return the
initial cursor window back to the client, potentially saving
an extra RPC. Because the communication protocol between
the CursorToBulkCursorAdaptor and BulkCursorToCursorAdaptor was
getting a little hard to follow, introduced a new type called
BulkCursorDescriptor to hold all of the necessary parameters.
Deleted several unnecessary IBulkCursor methods that are never
actually called remotely.

AbsListView was doing too many invalidates during scrolls/flings.
Some of them were also covering too large an area of the screen.

Earlier commit was incorrectly cloning the currentSyncs list, so it

This will be used to allow new features to be requested... such as,
say, a special kind of animation. Right now there are no options
defined.

The main performance improvement should come from the fact
that we entirely skip the loop (which calls getLineStart, getLineTop
and getLineDescent on each line) in the frequent case where there
are no LineBackgroundSpans.

Refactor SMS Cell Broadcast support to enable receiving CMAS warning
notifications over CDMA. The CellBroadcastReceiver app must also be
updated with the corresponding change. All cell broadcasts are now
delivered as a Parcelable SmsCbMessage object in the "message" extra
of the SMS_CB_RECEIVED_ACTION or SMS_EMERGENCY_CB_RECEIVED_ACTION,
instead of as a GSM/UMTS "pdu" byte array.
Existing functionality for ETWS and CMAS alerts over GSM/UMTS continues
to be supported using the new radio-technology independent SmsCbMessage
and related objects. Test cases are added to verify that valid and
invalid broadcast data is handled appropriately.
Unit testing discovered a bug in the BitwiseOutputStream utility class
used by the added test cases. When the BitwiseOutputStream object must be
expanded (in the private possExpand() method), the mEnd field is not
updated to the new array size. This causes a new array to be allocated
on every new write, and for all data beyond the original array allocation
to be replaced with zeroes. Fixed by adding a line to possExpand() to
update mEnd. Added a test case to BitwiseStreamsTest to verify the fix.
Besides the test cases, BitwiseOutputStream is only used by BearerData in
two places, both of which allocate a sufficient initial buffer. So the
bug in BitwiseOutputStream is not critical to fix for normal operation,
but should be fixed so that the test cases using it function correctly.
