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.

* 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.

The gralloc usage flags are an enum, which is backed by an
implementation defined type. Both gcc and clang are making this a long
long. All the values are hard coded to fit within 8 hex characters
though, so just make the cast.

Changes the call to IGBP::detachNextBuffer to return an
