AudioProductStrategies offers the possibility to dynamically
translate attributes to stream types (and vice versa) within
audio policy engine.
Legacy engine has hard coded rules to maintain the translation
service.
This patch removes the hardcoded translation within the helper
and replaces them by AudioProductStrategy APIs.
Test: AudioPolicyTests: AudioProductStrategiesAllStreamsTest
It loops on all stream types supported by strategy and ensures
device selection matches. Hard coded stuff would prevent right device
selection.

This CL adds required introspection APIs to deal with product strategies:
-getter of the collection of product strategies
-helper function to return the strategy associated to a given attributes.
This API is mandatory to avoid duplicating the logic that compiles the strategy
for a given Audio Attributes structure.

Make each extractor plugin export a list of file types it supports,
so we no longer need to hardcode such a list in the framework.
Test: manual
Change-Id: I1e41a5d477ea56960ad3e4bc35f5183c03c3fe3a
Remove support for intermediate extractor format versions
and leave only the 'V3' format, but remove 'V3' from the
names of the classes and structs involved, and reset the
version number back to 2 (version 1 is the C++ interface
shipped in P, which is no longer supported).

changed over to it.

It is no longer needed in libmediaextractor, and moving it back

Add a C API for DataSource/Base, and a helper so extractors
can continue using a C++ API.

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.

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.

Implement silencing of audio capture for idle UIDs for
MMAP streams.
Use audio HAL setMicGain() API to silence the mmap buffer for
exclusive mode and when only one client is active in shared mode.
Add new MmapStreamCallback method onStreamSilenced() for AAudio
service to selectively silence streams from silenced UIDs in
shared mode.

Prior to this CL, if an AudioTrack client wrote audio data after
AudioTrack stop(), but before the track was drained by the server,
the newly written client data would be consumed in the drain.
We now limit the server read to the client write position on stop.
This interlocking is essential for rapid asynchronous AudioTrack
command processing.

- Add MetaDataBase base class that MetaData derives from, but which
does not derive from RefBase.
- MediaBuffer::meta_data() now returns a MetaDataBase& rather than an
sp<MetaData>
- Rename MediaSourceBase to MediaTrack.
- MediaSource no longer derives from MediaSourceBase (or MediaTrack)
- MediaTrack::getFormat(), MediaExtractor::getTrackMetaData() and
MediaExtractor::getMetaData() all take a MetaDataBase& parameter that
they fill out, rather than returning a MetaData directly (the
corresponding methods on MediaSource and RemoteMediaExtractor continue
to return MetaData)
