Fix issue with call backs from media process.
All but a few lines of this is for issue #16013164, which allowed
apps to do some operations as the media uid by having it call
back to them to open a file. The problem here is with the tempory
identity stuff in the activity manager, allowing us to make the open
call as the original caller... ideally we should figure out a way
to just get rid of all of that, but the solution here is actually
easier (even though it doesn't look it) -- we now hand a token over
to the openFile() call that it can use when doing permission checks
to say "yes I would like the check to be against whoever is responsible
for the open". This allows us to do the uid remapping for only this
one specific set of permission checks, and nothing else.
Also fix issue #17487348: Isolated services can access system services
they shouldn't be able to. Don't send any system service IBinder objects
down for the first initialization of an isolated process.

Work on issue #10130785: Restore silence and vibrate settings...

Add a new ContentProvider API to canonicalize URIs, so they can
be transported across backup/restore.

Add CancellationSignal support to file operations.
Since ContentProvider file operations can end up doing substantial
network I/O before returning the file, allow clients to cancel their
file requests with CancellationSignal.
Ideally this would only be needed for openFile(), but ContentResolver
heavily relies on openAssetFile() and openTypedAssetFile() for common
cases.
Also improve documentation to mention reliable ParcelFileDescriptors
and encourage developers to move away from "rw" combination modes,
since they restrict provider flexibility. Mention more about places
where pipes or socket pairs could be returned.
Improve DocumentsContract documentation.

More work on App Ops service.
Implemented reading and writing state to retain information
across boots, API to retrieve state from it, improved location
manager interaction to monitor both coarse and fine access
and only note operations when location data is being delivered
back to app (not when it is just registering to get the data at
some time in the future).
Also implement tracking of read/write ops on contacts and the
call log. This involved tweaking the content provider protocol
to pass over the name of the calling package, and some
infrastructure in the ContentProvider transport to note incoming
calls with the app ops service. The contacts provider and call
log provider turn this on for themselves.
This also implements some of the mechanics of being able to ignore
incoming provider calls... all that is left are some new APIs for
the real content provider implementation to be involved with
providing the correct behavior for query() (return an empty
cursor with the right columns) and insert() (need to figure out
what URI to return).

Implement a cancelation mechanism for queries.
Added new API to enable cancelation of SQLite and content provider
queries by means of a CancelationSignal object. The application
creates a CancelationSignal object and passes it as an argument
to the query. The cancelation signal can then be used to cancel
the query while it is executing.
If the cancelation signal is raised before the query is executed,
then it is immediately terminated.

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.

Add new ContentProvider for doing conversions to data streams.
This introduces basic infrastructure that should allow content
providers holding complex data to perform on-demand conversion
of their data to streams of various types. It is achieved through
two new content provider APIs, one to interrogate the possible
stream MIME types the provider can return, and the other to
request a stream of data in a particular MIME type.
Because implementations of this will often need to do on-demand
data conversion, there is also a utility intoduced in ContentProvider
for subclasses to easily run a function to write data into a
pipe that is read by the client.
This feature is mostly intended for cut and paste and drag and
drop, as the complex data interchange allowing the source and
destination to negotiate data types and copy (possible large)
data between them. However because it is fundamental facility
of ContentProvider, it can be used in other places, such as for
more advanced GET_CONTENT data exchanges.
An example implementation of this would be in ContactsProvider,
which can now provider a data stream when a client opens certain
pieces of it data, to return data as flat text, a vcard, or other
format.

Add "call" method on ContentProvider.
This permits implementing interfaces which are faster than using
remote Cursors. It then uses it for Settings & SettingProvider, which
together account for ~50% of total ContentProvider event loop stalls
across Froyo dogfooders.
For fetching Settings this looks like it should reduce average
Settings lookup from 10 ms to 0.4 ms on Sholes, once the
SettingsProvider serves most gets from in-memory cache. Currently it
brings the Sholes average down from 10ms to 2.5 ms while still using
SQLite queries on each get.
