Print services setting changes not handled for managed profiles.
We keep per user settings for enabled print services which are
observed to update the print manager service state. We were listening
to all user changes but the handling code was not updating the state
of the user whose settings changed, rather the current user.
Added hidden APIs in content observer to know which user changed
and now the print manager serivce handles content changes for the
correct user.

Fix cursor window leak when query execution fails.
Ensure that the Cursor object is closed if a query on a
content provider fails due to an error or is canceled during
execution. There are several places in the code where
similar problems can occur.
To further reduce the likelihood of leaks, close the cursor
window immediately when a query fails.

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.

Inform ContentObservers about the changed content Uri.
Added a new method ContentObserver.onChange(boolean, Uri) that
receives the changed content Uri. This can help applications make
better decisions about how to interpret a change notification.

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.

Add a CrossProcessCursorWrapper.
Bug: 5220669
The CrossProcessCursorWrapper is a useful building block
for wrapping cursors that will be sent to processes remotely.
It can also transform normal Cursors into CrossProcessCursors
transparently.
The new class fixes common performance problems and bugs
that applications have encountered when implementing
ContentProviders.

AbstractWindowedCursor is not special.
Use the CrossProcessCursor interface in the way it was intended
without introducing special cases for AbstractWindowedCursor.
This is possible now that we do not distinguish between local-only
and remotable CursorWindows so we don't need to provide a window
to the AbstractWindowedCursor for it to fill; it can provide one
for itself if it wants one.
This logic makes it possible to create CrossProcessCursor
implementations that perform just as well as AbstractWindowedCursors.

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.
