Adds support for hardware buffers in ImageWriter Images.
This allows dequeuing private image buffers from ImageWriters,
and accessing their hardware buffers.

Camera: Populate Image tranformation in reader and writer
"ImageReader" and "ImageWriter" must pass information about the
specific buffer transformation.
Currently only the "ImageReader" implementation of the
"android.media.Image" abstract classs will populate the
corresponding transformation, the remaining implementations will
use the default identity tranformation.

ImageWriter: Attach non-opaque Images as well.
With all the work under the hood of ImageReader/Writer in the last few
releases, this is much more straightforward to enable.
Only trick is to ensure that the Image detached from the ImageReader
correctly clears out its planes, if present.

ImageReader/Writer: Only register 1 buffer for native allocation
Registering with the maximum potential memory made by visible by an
ImageReader/Writer can cause the VM to try to heavily garbage-collect
the rest of the application. This can have significant impact on camera
applications, since they often have large ImageReader/Writer queues.

ImageReader/Writer: refactor and cleanup
Below changes are included:
* Defer the buffer lock to Image#getPlanes call. This will save quite a bit
CPU cycles associated with lock buffer if the application doesn't really
want to access the data.
* Refactor the code: move some common code to some utility class, and use
one unified consumer (BufferItemConsumer) in ImageReader native implementation.
The code refactoring will also make it easier to support non-opaque image
attach/detach.

media: improve ImageReader/Writer native memory management
* Hook up the native allocation registration with ImageWriter, such that GC
can get some hint when clean up the large memory object.
* Close all pending images when closing ImageReader. This could avoid native
mem leaks for some bad app practice. For example, some apps may hold images
in background service when activity is paused/destroyed, which could cause
huge native memory leaks even ImageReader is closed.
* make Image close thread safe: it is possible the clients close the image
in listener thread and the client main thread.
* Some minor code refactor to reduce the code duplication.
