Added here is the header file that defines HDMI-CEC HAL interface.
Its main purpose is to support major CEC features such as 'one touch
play', 'standby' for playback device. But basic skeleton for supporting
other kinds of devices(like TV) is also in place.

There's a discrepancy in the order of arguments between the interface
and the implementation. bluedroid swaps the |error| and |local_role|
arguments when calling back so this change redefines the interface

For wrapping the disk encryption secret, we add a flag that indicates it
can be done without having to start some storage daemon which the
trusted OS will query to get data needed to load up the keys. This
usually means that the "key blob" we store is actually just the RSA key
encrypted with the device's KEK and not a reference to an encrypted
filesystem stored on /data
Also to allow other providers to upgrade to V3 of the header, we add
flags to show whether the keymaster supports different key types. This
allows keymaster HALs to support the whole device encryption secret
wrapping without needing to implement DSA and EC key handling. The V2
header made support implicit.

Align camera2's management of platform-opaque formats with rest of
framework. Instead of using CAMERA2_PIXEL_FORMAT_OPAQUE, use
HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED as the format for both the
camera HAL and for gralloc, and depend on the gralloc usage flags to
let the gralloc module select the appropriate real format for specific
stream endpoints.
Add a new gralloc usage for ZSL mode, where the camera service will
hold a streaming circular buffer of opaque full-resolution images
during camera preview. Since this is an opaque format that needs to be
optimized for 30fps operation, need gralloc to be aware of this use
case.

During the HWC 0.x evolution, some fields were left optional or
organized strangely to avoid breaking backwards compatibility. Since
we're breaking it in the transition to HWC 1.0 anyway, we can clean
these up a little.
* The current callbacks are now registered immediately after the
device is opened and guaranteed to be present, so the implementation
can rely on them being present.
* The hwc_methods_t structure is gone, with its two methods folded
into the main hwc_composer_device_1_t.
* All methods and callbacks are now required except dump(). New
methods and callbacks we add in the future will still be optional
for backwards compatibility.

disable hardware composition, though that wasn't documented. Now
we'll call prepare with non-NULL pointers but the layer list will
have zero layers.
* Set won't be called with NULL pointers. This used to cause the
display to turn off; that is now done by calling the blank() method,
which is no longer optional.
