This causes frequent programming errors, when developers assume
that holding onto a Surface will keep its associated SurfaceTexture,
ImageReader, etc, also alive.

This method (currently @hide) discards all cached buffers for
the ImageReader, which can be useful to free up memory at the
cost of reallocationt time if more buffers are needed later.
It has no effect on acquired Images, filled Images waiting to be
acquired, or buffers being actively used by the source rendering to the
Surface.

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.

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.

The application could acquire images in onImageAvailable callback when
the ImageReader is being closed. We need some protection here to avoid
application crash.

* 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.

Mostly due to no standard stream configurations being defined,
and for the correct overrides for DEPTH_POINT_CLOUD format.

Estimate the native allocation and register it so it can be
accounted for during GC.

Attempting to access an Image after it is closed will result in an ISE.
Also fixed some minor doc issues.

ImageWriter/Reader API change, including below changes
* Interface for Opaque ImageReader
* ImageWriter Interface and implementation
* Image class minor update to support ImageWriter opaque ImageReader
detach/attach interface are defined but yet to be implemented.

- Add an explicit mapping between public ImageFormat/
PixelFormat enums and internal HAL format/dataspace.
- Add DEPTH16 and DEPTH_POINT_CLOUD formats
- Wire up mapping layer to ImageReader to support depth
formats

certain devices for JPEG (blob) format buffers.

This avoids a race where close() can return while there are still
onImageAvailable callbacks pending.

- No longer return null when some bad error happens
- Throws OutOfResourcesException when images need to be closed
- Throws IllegalStateException when an unknown internal error happens

- New core API classes in android.hardware.photography
- android.media.Image and android.media.ImageReader classes for
application access to direct hardware image buffers.
- Additions to android.graphics.ImageFormat to describe new image
types needed by new camera API.
- Some documentation included; very little implementation.
