Use myUserId() only in registerContentObserver()
The reason for this is a bit subtle: we want to guarantee that
when a content observer is registered using the public API, it
is *always* bound to the host user's view of the data behind the
observed Uri, never the calling user's. Now, the reason it was
the calling user in the first place is that the Settings provider
(and potentially any singleton provider) needs the observers
underlying Cursors returned from query() to be tied to the caller's
user, not the provider's host user.
In order to accomplish that now that the public-facing behavior is
always tied to the host user, the concrete class that implements
the Cursor type handled by the Settings provider has been extended
with a new hidden API for setting a notification observer tied to
an arbitrary user; and then the provider explicitly downcasts the
query result's Cursor to that class in order to register the
notification observer. We can do this safely because this is platform
code; if we change the way that these underlying cursors are constructed,
we can just fix this point of call to follow along. If they get out
of sync in the future, the Settings provider will scream bloody
murder in the log and throw a crashing exception.

Merge "Fix cursor memory leak"

Fix cursor memory leak
In current code, if an application opens a cursor to access a
provider, and doesn't close that cursor, later, when this cursor
is garbage collected, it won't get closed. This will cause a memory
leak in the provider. The leaked memory can only be reclaimed when
the application with the leaked cursor was dead.
The solution is, close the cursor when it's garbage collected.

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.

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.

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.
