Overhual DvrBuffer and DvrBufferQueue API: Step 1
Adding new APIs:
dvrWriteBufferQueueGainBuffer
dvrWriteBufferQueuePostBuffer
dvrReadBufferQueueAcquireBuffer
dvrReadBufferQueueReleaseBuffer
Those new APIs streamlines DVR buffer operations:
1/ It allows static Dvr{Read,Write}Buffer objects to be statically
allocated with the queue.
2/ Symentric Gain/Post on WriteBufferQueue and Acquire/Release on
ReadBufferQueue.
3/ Use fixed buffer metadata.
4/ This is also a prerequisite to using shared memory based metadata and
async buffer IPC.
More details and discussion at: go/gvr-async-bufferhub
Special note regarding DVR API order in this CL: The new buffer queue
API entries are inserted before new PoseClient API as the PoseClient is
still blocked from being released and the new BufferQueue APIs are
expected to be released sooner than that.

Add dvr API to create write queue locally
Currently, this API is mostly for testing purpose. But also note that
this API might eventually deemed useful if BufferHub-based ANativeWindow
becomes binder parseable.

Add dvrReadBufferQueueGetEventFd
We need to expose the read queue's event fd, so that a caller can epoll
on a set of queues' fd for efficient buffer acquisition.

dvrReadBufferQueueDequeue: allow empty metadata
Currently, when there is no metadata on the read buffer queue, we have
to pass in dummy out_metadata; otherwise the API always return
-EINVAL. This CL allows (nullptr, 0) as legit input and add test to
cover that.

DvrBufferQueue: Add basic event callbacks
Currently, there is no guarantee of thread safty and on which thread
those callbacks are going to be fired.
Three new DVR APIs introduced:
1/ dvrReadBufferQueueSetBufferAvailableCallback
2/ dvrReadBufferQueueSetBufferRemovedCallback
3/ dvrReadBufferQueueHandleEvents

DvrWriteBufferQueue: support buffer resizing
Currently, the buffer resising is implemented at the C API's
implementation level, i.e. it's a pure client side logic out of the core
BufferHubQueue C++/PDX implementation. The logic is similar to
BufferHubQueueProducer's buffer resizing logic.
Other minor changes:
1/ Use ProducerQueueConfig in DisplaySurface as well, and plumb default
width, height, and format to bufferhubd when a BufferHubQueue is created
through a Display Surface.
2/ Added detailed dvr_buffer_queue comments.
3/ Since we now have more and more logic in dvr_buffer_queue, refactored
Dvr{Read,Write}BufferQueue to be C++-styled class.

Remove the VR compositor from the framework.
Remove the VR compositor framework and enable out-of-process VR composition
in VrCore.
This CL seems large due to the ripple effect of changing the VrFlinger
API and protocol types. There are three major modules that require
concurrent changes:
1. Protocol definitions and low-level VrFlinger API in libdisplay.
* Additional changes needed to keep old interfaces working for
a short time while replacing the dependent code (dvrGraphics*).
2. VrFlinger service implementation changes to support VrCore compositor
and the removal of the internal compositor.
3. Changes to libdvr platform library API due to changes in #1 and #2.
Because of the nature of the interdependence of types and other defs it is
difficult to break this CL into smaller chunks. However, review of the three
major modules (libdisplay, libdvr, and libvrflinger) may be done separately
to ease the mental burden on reviewers.
Change Summary:
- Remove obsolete screenshot service. VR screenshots will be implemented
by VrCore.
- Update display protocol definitions for changes in VrFlinger service
requirements. The majority of the changes in libdisplay are a
consequence of these protocol and service changes.
- Update VrFlinger to support two kinds of surfaces:
1. Application - use by VR apps.
2. Direct - used by VrCore (protected by permission check).
- Remove VrFlinger internal compositor and GL context.
- Remove obsolete debug console.
- Update VrFlinger hardware composer interface to handle direct
surfaces only, removing the concept of GPU (compositor) layers.
- Update display manager to expose access to application surface info
to VrCore (protected by permission check).
- Update libdvr platform library interfaces for changes to VrFlinger
API / protocol.
- Clean up libdvr API struct setup using a common include.
- Add C++ header-only helpers for DVR platform library opaque types.
Bug: 36401174
Test: Build; run VrFlinger display test tool.

dvr_api GetExternalSurface returns ANativeWindow
Now that we have a public NDK API to convert an ANativeWindow to a Java
Surface, we no longer need to mess with Jni and libandroid_runtime in
libdvr.
See more information at:
http://ag/#/q/topic:ANativeWindow_toSurface+(status:open+OR+status:merged)
Also, as a side effect, we are now free to convert this library to use
Android.bp (though we probably want to hold off for a while).

Return jobject when getting android Java Surface
This logic is originally borrowed from similar API from shim_gvr API
where we cannot explicity deps on JNI.h in the public header. This
constrain no longer exists as libdvr is an Android platform library.
