gralloc_gbm: Quiet logcat verbosity

When using gralloc_gbm, especially playing yuv video, there's tons
of log noise like:

09-17 05:46:12.823 494 2001 D GRALLOC-GBM: handle 0xb400006d6a4d4380, hnd 0xb400006d6a4d4380, usage 0x33
09-17 05:46:12.824 494 2001 I GRALLOC-GBM: lock bo 0xb400006d7a4a26f0, cnt=0, usage=33

over and over.

So set these two messages to verbose via ALOGV.

Support getting offsets via lock_ycbcr()

When no software access usage flag specified,
.lock_ycbcr() should return NULL pointer based plane addresses,
which mesa3d interprets as offsets.

gralloc_gbm: add .lock_ycbcr to support video playback use case

The .lock_ycbcr function hook is currently missing from gralloc driver,
and that stops video playback from working. Add a .lock_ycbcr function
implementation to get SW video playback test start working, where
HAL_PIXEL_FORMAT_YV12 format is used/tested.

gralloc_gbm: Handle null crop values

gralloc_gbm: Handle null crop values

Yongqin recently reported an issue here:

Where the CTS VirtualDisplayTest is failing on db845c.

The trace looks like this:
arm64-v8a CtsDisplayTestCases[instant]: Instrumentation run failed
due to 'Process crashed.'
Crash Message:lock buffer failed for format 0x1
java.lang.RuntimeException: lock buffer failed for format 0x1
at android.media.ImageReader$SurfaceImage.nativeCreatePlanes(Native Method)
at android.media.ImageReader$SurfaceImage.getPlanes(ImageReader.java:898)
at android.display.cts.VirtualDisplayTest$ImageListener.scanImage(VirtualDisplayTest.java:381)
at android.display.cts.VirtualDisplayTest$ImageListener.onImageAvailable(VirtualDisplayTest.java:364)
at android.media.ImageReader$ListenerHandler.handleMessage(ImageReader.java:798)
at android.os.Handler.dispatchMessage(Handler.java:106)
at android.os.Looper.loop(Looper.java:216)
at android.os.HandlerThread.run(HandlerThread.java:67)

What seems to be happening, is that the call chain looks like:

in frameworks/base/media/jni/android_media_ImageReader.cpp:
nativeCreatePlanes() ->
Image_createSurfacePlanes() ->
Image_getLockedImage() ->
Which then calls the other lockImageFromBuffer() with a uninitialized
bufferItem->mCrop value:

That then calls: buffer->lockAsync(inUsage, rect, &pData, fenceFd);

which calls into gralloc::lock() in the gralloc_gbm implementation.

gralloc_gbm::gralloc_gbm_bo_lock() calls gbm_map():

gralloc_gbm::gbm_map() calls gbm_bo_map():

Which returns an error if height or width is zero:

While not common, since some users are passing null crop rects,
I propose we consider null crop rects to be the same as the
entire buffer.

Thus this patch special cases these null rects and changes the
width and height value to be the full buffer width and height.

With this patch, the affected CTS tests no longer fail.
