Init the static member when first used for CursorWindow.
As the CursorWindow will be preloaded by zygote, and there is one static
member need use the system resource to initialize. But actually the zygote
do not preload the resource now. (In fact, the zygote will preload classes
first, then preload the resource.) We need ensure the zygote to create the
system resource first.
So change to init this static member as -1, and it will be evaluated when
first used.

AArch64: Use long for pointers

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.

by avoiding redundant string conversions for numeric datatypes.

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.

the reason for bug:3281533, bug:3127159 is probably too many cursors are left
un-closed in the process.
print the info on the number of cursors left open when the exception
"cursorwindow allocation failed" occurs.
This should help us figure out if that indeed is the reason
and which process is leaving the cursors open.

two bugs were introduced by the above CL
1. to test if the column value is NULL, getType_native() should check if
the columnindiex is valid. (it seems sometimes callers could ask if a
given non-existent column is null - and the answer should be true.)
2. if a column is null and isBlob_native, isString_native methods should
return true - not false.

Speed up ContentProvider.query() in simple case by ~30%
When query() uses bulkQuery() and we know we're going to need some
metadata right afterwards (number of rows and column index of _id, if
present), just asked for it in the initial binder transaction instead
of immediately fetching it again.
Also, this defers loading column names until the client asks for them.
This gets down the simpler (and very common) use cases of
ContentProvider.query() down to 3 binder calls:
QUERY_TRANSACTION to android.content.ContentProvider$Transport
GET_CURSOR_WINDOW_TRANSACTION to android.database.CursorToBulkCursorAdaptor
CLOSE_TRANSACTION to android.database.CursorToBulkCursorAdaptor
More can still be done, but this is a good bite-sized first piece.
