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.

Use a MemoryHeapBase directly instead.

This patch modifies the native binder interface to the metadata
retriever to pass the caller's thread group across the binder
interface. On the server side, the thread scheduler group is
set to the caller's scheduler group temporarily and restored
after the request has completed. This patch also reverts a
previous patch where the priority of the thread was forced to
a low priority foreground thread.
This should give apps more control over the priority of their
metadata retrieval, particularly allow background process to
run without hogging the CPU.

This change forces metadata retreiver threads to background priority.
Uses an inner class to encapsulate the priority change so that it
automatically restores priority when returning to the client.

1. mRetriever was initialized twice: one in the constructor and the other in the setDataSource
2. cached the mode so that setMode can still be called before setDataSource.
mRetriever won't be initialized until data source is set; thus we have to do this
