Deprecate local-only CursorWindows.
There is no difference and has never really been a difference
between local-only and remotable CursorWindows. By removing the
distinction officially in the API, we will make it easier to
implement CrossProcessCursor correctly. CrossProcessCursor
is problematic currently because it's not clear whether a call
to getWindow() will return a local-only window or a remotable window.
As a result, the bulk cursor adaptor has special case handling
for AbstractWindowedCursors vs. ordinary CrossProcessCursors
so that it can set a remotable window before the cursor fills it.
All these problems go away if we just forget about local-only
windows being special in any way.

Use ashmem for CursorWindows.
Bug: 5332296
The memory dealer introduces additional delays for reclaiming
the memory owned by CursorWindows because the Binder object must
be finalized. Using ashmem instead gives CursorWindow more
direct control over the lifetime of the shared memory region.
The provider now allocates the CursorWindows and returns them
to clients with a read-only protection bit set on the ashmem
region.
Improved the encapsulation of CursorWindow. Callers shouldn't
need to care about details like how string fields are allocated.
Removed the compile-time configuration of string and numeric
storage modes to remove some dead weight.

Fix ownership of CursorWindows across processes.
Bug: 5332296
Ensure that there is always an owner for each CursorWindow
and that references to each window are acquired/released
appropriately at all times.
Added synchronization to CursorToBulkCursorAdaptor to
prevent the underlying Cursor and CursorWindow from being
remotely accessed in ways that might violate invariants,
resulting in leaks or other problems.
Ensured that CursorToBulkCursorAdaptor promptly releases
its references to the Cursor and CursorWindow when closed
so they don't stick around longer than they should, even
if the remote end hangs onto the IBulkCursor for some reason.
CursorWindow respects Parcelable.FLAG_WRITE_RETURN_VALUE
as an indication that one reference to the CursorWindow is
being released. Correspondingly, CursorToBulkCursorAdaptor
acquires a reference to the CursorWindow before returning
it to the caller. This change also prevents races from
resulting in the transfer of an invalid CursorWindow over
the wire.
Ensured that BulkCursorToCursorAdaptor promptly releases
its reference to the IBulkCursor when closed and throws
on attempts to access the cursor while closed.
Modified ContentProviderNative to handle both parts of
the wrapping and unwrapping of Cursors into IBulkCursors.
This makes it a lot easier to ensure that the right
things happen on both ends. Also, it turns out that
the only caller of IContentProvider.bulkQuery was
ContentProviderNative itself so there was no need
to support bulkQuery on ContentProviderProxy and it was
just getting in the way.
Implement CloseGuard on CursorWindow.

Clean up CursorWindow lifetime.
Bug: 5332296
Removed dead code in SQLiteCursor related to the use of a background
query thread. This code could result in CursorWindows being modified
concurrently or used after free. This code is broken, unused and
is just in the way.
Added comments to explain how CursorWindow ownership is
supposed to work for AbstractWindowedCursors. (There are still cases
where cursor windows get dropped on the floor without being closed.
Those will be taken care of in a subsequent patch.)
Cleaned up SQLiteQuery.fillWindow to eliminate duplicate code and
remove bits that were only needed for background loading, like
returning -1.

- create a new generic ISyncAdapter implementation, SyncAdapterNew
- change the applyBatch to take an ArrayList rather than an []
- change Entity to be a final flass that contains ContentValues
- remove the ability to update/insert Entities by a ContentProviderOperation
