This change renames the IMemory raw pointer accessors to
unsecure*() to make it apparent to coders and code reviewers
that the returned buffer may potentially be shared with
untrusted processes, who may, after the fact, attempt to
read and/or modify the contents. This may lead to hard to
find security bugs and hopefully the rename makes it harder
to forget.
The change also attempts to fix all the callsites to make
everything build correctly, but in the processes, wherever the
callsite code was not obviously secure, I added a TODO requesting
the owners to either document why it's secure or to change the
code. Apologies in advance to the owners if there are some false
positives here - I don't have enough context to reason about all
the different callsites.
Test: Completely syntactic change. Made sure code still builds.

Allow sequential frame retrieval to reuse the decoder without
re-init and re-seek.
Get rid of IMediaMetadataRetriever api that retrieves multiple
frames at a time, this method could hold up more memory than
what's needed, because the client side has to copy the frames
to a separate set of bitmaps anyways.
This change is needed to support animation Drawbles efficiently
which typically get one frame at a time.

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.

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.

- MediaSource, DataSource and MediaExtractor are moved to
libmediaextractor so that they can be used by extractor
implementations without depending on libmedia and libstagefright.
- XXXFactory classes has been added in order not to expose CreateXXX
methods in libmediaextractor.
- avc_utils is moved to libstagefright_foundation since most of
extractor implementations are relying on that.

than mp4.

IMediaMetadataRetriever::setDataSource(fd, offset, length) takes the ownership
of |fd| on the direct invocation, and doesn't take the ownership on invocation
from Binder. This is inconsintent to other similar methods like
IMediaPlayer::setDataSource, and causes potential double close of |fd|.
This CL changes the caller and implementations to leave the ownership to make
them consistent.
Also, fixes a double close in IMediaPlayerService::setDataSource in an error
case.

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.

Add the ability to dynamically register low level MediaPlayer
factories which will be probed at setDataSource time to determine the
proper MediaPlayerBase to instantiate.
This change is in preparation for moving libaah_rtp out of
frameworks/base and into phantasm platform directory.

At some point the implementation became complicated because of
SurfaceFlinger's special needs, since we are now relying on gralloc
we can go back to much simpler MemoryDealer.
Removed HeapInterface and AllocatorInterface, since those don't need
to be paramterized anymore. Merged SimpleMemory and Allocation.
Made SimplisticAllocator non virtual.
Removed MemoryDealer flags (READ_ONLY, PAGE_ALIGNED)
Removed a lot of unneeded code.
