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. Change-Id: Ib3c8305d3cc62322f38a06698d404a2989bb6ef9

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.

Retry test-runner tests move. This time change the frameworks makefile so it only includes test-runner/src in the public API.

Move framework test-runner unit tests to be closer to their source. Move the test-runner source into a separate src folder to accommodate the test move.
