Decode one row of tiles at a time for image that has tiles
Add an api to IMediaMetadataRetriever to decode image rect.
It will reuse the same full frame IMemory, and decode only
the requested rect. For now, StagefrightMetadataRetriever
will only allow decoding of rect that's a full row of tiles,
and the requested must be issued sequentially (i.e. no
arbitrary rects). When the extract side is fixed to allow
seeking by tiles, it can be extended to allow arbitrary
rects.
This allows HeifDecoderImpl (on client side) to start
processing the getScanlines in parallel with the decoding.
Test: CTS MediaMetadataRetrieverTest;
Manual testing of HEIF decoding of files with or without tiles;
Manual testing of HEIF thumbnails generation in Downloads app.

Remove one redundant frame copy in MetadataRetriever
When extracting bitmaps, MediaMetadataRetriever does a copy from
StagefrightMetadataRetriever's VideoFrame to IMemory. We could
just allocate IMemory directly and return that to the client.

heif: fixes for image sequences and dual-function files
Adding support for two new sets of APIs on MediaMetadataRetriever:
- getImageAtIndex() and getPrimaryImage()
- getFrameAtIndex() and getFramesAtIndex()
Outline of changes:
- Proper indexing of all displayable still images, so that they
can be retrieved by getImageAtIndex()
- Exposing still images as "image/x.android.heic" tracks in
MediaExtractor with necessary descriptive keys (such as "grid-*")
- Support to retrieve video frames by absolute index instead
of timestamps, as image use cases mostly are interested in
getting the images and care less about timing.
- Support to retrieve video frames in batches because retrieving
one frame at a time is inefficient.
- Refactor image / frame decoding code into FrameDecoder, and split
still image decoding and video sequence decoding into to sub
classes to facilite future development.

stagefright: MetadataRetriever API to specify mime and color format
- Allow setDataSource() to specify mime. In case of HEIF decoding
request from skia, we don't want to sniff any other format other
than mp4.
- Allow getFrameAtTime() to specify dst color format.

Extractor service
Run extractors in a separate process. Currently all data is copied through a
binder transaction, and WVMExtractor is still run in the mediaserver process.

Unhide the android.media.[Media]DataSource interface.
This allows apps to implement MediaDataSource, which is modeled on
stagefright's DataSource, to supply media data to the framework. This
was already implemented for MediaExtractor, but it was renamed from
DataSource.
MediaExtractor, MediaPlayer and MediaMetadataRetriever each have a new
overload: #setDataSource(android.media.MediaDataSource)
Only NuPlayer supports this new data source.
The change introduces:
* IDataSource: The binder interface for DataSource.
* JMediaDataSource: The native counterpart to the java interface. It
implements IDataSource.
* CallbackDataSource: A stagefright DataSource that wraps an
IDataSource.
