Add additional Method that check whether a table is empty or not
Application Devleopers are using queryNumEntries API
implemented by "COUNT(*)" to check whether a table is empty or not.
COUNT(*) has to process the entire table to compute the result.
But, "EXISTS" can stop after a single matching row has been found.
So, Using "EXISTS" is more faster than "COUNT(*)"
I added new API using "EXISTS" to check whether a table is empty or not

Deprecate DatabaseUtils.InsertHelper.
This class does not offer any advantages over SQLiteStatement
and just makes code more complex and error-prone.
Documented that the class is not thread-safe.
Removed a potential deadlock in insert() and replace() caused
by the insertInternal() method being synchronized in the case
where the class was being used concurrently (woe to you!).
Thread A would start a transaction.
Thread B would call insertInternal() and acquire the object monitor,
but block because it could not obtain the db connection because
thread A is holding onto it.
Thread A would call insertInternal() and block because Thread B
was holding the object monitor.
Deadlock.
Changed this code to use a transaction instead of a lock,
which provides the necessary mutual exclusion guarantee without
the potential for a deadlock. Even so, the class really isn't
thread safe.

Prefetch column names in bulk cursor adaptor.
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.

Don't close the database until all references released.
SQLiteDatabase.close() should call releaseReference() rather than
closing the database immediately. SQLiteDatabase should also hold
a reference to itself while performing certain operations to
ensure that they complete normally even if another thread closes
the database at the same time.
Fixed a couple of missing or redundant uses of acquireReference()
related to CursorWindows.
To be honest, the reference counting performed by SQLiteClosable should
not be needed, but we're stuck with it in the API.

Optimize fillWindow to improve reverse-seek performance.
Bug: 5520301
When an application requests a row from a SQLiteCursor that
is not in the window, instead of filling from the requested
row position onwards, fill from a little bit ahead of the
requested row position.
This fixes a problem with applications that seek backwards
in large cursor windows. Previously the application could
end up refilling the window every time it moved back
one position.
We try to fill about 1/3 before the requested position and
2/3 after which substantially improves scrolling responsiveness
when the list is bound to a data set that does not fit
entirely within one cursor window.

Make default implementation of fillWindow typesafe.
Bug: 5218310
This change fixes problems calling the default fillWindow
on Cursors that contain BLOBs. It should also be more efficient
by avoiding redundant string conversions for numeric datatypes.

Implement issue # 3255887 could CursorLoader offer...
...to throttle contentobserver-based requeries
Why yes, I guess it could.
This also reworks AsyncTaskLoader to not generate multiple
concurrent tasks if it is getting change notifications before
the last background task is complete.
And removes some of the old APIs that had been deprecated but
need to be gone for final release.
And fixes a few little problems with applying the wrong theme
in system code.

StrictMode: gather and return violating stacks in Binder replies
Now, when Thread A has a strict mode policy in effect and does a
Binder call to Thread B (most likely in another process), the strict
mode policy is passed along, but with the GATHER penalty bit set which
overrides other policies and instead gathers all offending stack
traces to a threadlocal which are then written back in the Parcel's
reply header.
