Use change in HWC_GEOMETRY_CHANGED flag appropriately to avoid
redundant and unintentional overwrites of DisplayFrame values,
which may result fall back to GPU.

* Mdss driver supports DMA-Multiplexing on wb interface
for certain targets. Add overlay get function to query
this info during pipe allocation for wb.
* UI Scaling on external is not supported on certain
targets due to the lack of availability of pipes with
scalars. Add overlay get function to query this info
to disable action-safe calcs, DRC and others which
require downscaling.

* Set DMA state at the start of the composition cycle
based on the following.
Set it to LINE_MODE if the number of active rotator
sessions are 0.
Set it to BLOCK_MODE if
** A yuv-layer for any display-device requires rotation
** (or) mExtOrientation is set
** (or) mBufferMirrorMode is set
* Separate out the reset helper function into more
modular ones

* Provide a binder interface call for wfd module
to inform display about the start/stop/pause/resume
of wfd session.
* This is needed for wfd-hdmi synchronization in
case of v4l2 wfd solution. If hdmi is plugged
in during v4l2 wfd session, display-hal waits in
uevent thread for wfd teardown notification from
wfd module, before going ahead with configuring
external display.
* For VDS WFD solution, display-hal waits in uevent
thread for wfd-teardown to be signalled from
the composition thread.

The display view frame needs to be set before calling trimLayer api
because it uses view frame to find the scissor for display, which is
used to clip crop for out-of-bounds display frame sent by framework.
If mViewFrame is not set, scissor will be empty rect, which leads to
wrong source crop calculation.

Add rotator obj to the layer-rot-map soon after its successfully
acquired. This makes sure that any object allocated is accounted
for, irrespective of whether rotator configuration succeeds or not.

1. Set the GPU hint flag to high for MIXED/GPU composition only for
first frame after MDP to GPU/MIXED mode transition.
2. Set the GPU hint to default if the current composition type is GPU
due to idle fallback or MDP composition.

Add support to turn the MDP downscale feature ON through the
use of a system property. 'sys.hwc.mdp_downscale_enabled' shall be
set to 'true' in build.prop file to enable this functionality.
This is required for OEMs that might have privacy concerns over panel
size information being exposed.

YUV layer display positions are mapped to primary resolution
[e.g. 1920x1080] when MDP downscale is enabled, that needs to be
transformed to the original external resoltion [e.g. 1280x720].
This transformation is not taken care for 4kx2k YUV use case.

* In some use-cases, it is possible that there are
no AppBuffer layers on the external/virtual layer-list
during which all the pipes will be allocated to the
primary. When layers do comeup on external/virtual
layer-list, subsequent overlay sets fail.
* This change ensures that in such cases, we invoke a
padding round on all the displays to free up the
hw resources which can be used in subsequent cycles.

Previously, the acquire and release fences for BLIT
composition were populated using same logic as Overlay,
but BLIT composition consists of separate BLIT step
before screen refresh, and app buffers are no longer
required after BLIT. So holding the buffers for both
the steps is unnecessary and impacts performance.
This change adds condition for BLIT in fence population
logic in hwc_sync and populates the right fences for the
App Buffers and Display Refresh during BLIT composition.

Vpuclient is the client side for VFM in hwc. It follows the
similar pattern of prepare and draw. It has 2 step prepare
including: setVpuSession and prepare. The setVpuSession function
passes all the layers from the SF list to VFM, which marks
the layers that it can support. After this, the layer
allocation/configuration is done, and finally in prepare the
allocated pipes are passed down to VFM. The draw function
passes the handle to the VFM to draw the video layer.

* Useful to estimate GPU/MDP performance for different resolutions.
* MDP:
Every layer is downscaled/upscaled to primary panel resolution.
* GPU:
All layers will be composed in required resolution to FB.
FB is downscaled/upscaled to primary panel resolution.
* Steps to follow:
step 1: adb root
step 2: adb shell setprop debug.hwc.fbsize XRESxYRES
step 3: adb shell stop
step 4: adb shell start

Added a new layer flag: HWC_VPU_PIPE to indicate that the layer
will be drawn by VPU. There is a corresponding MDP pipe
flag: MDP_VPU_PIPE, which should be set for the VPU layers to
indicate the layer will be drawn by VPU, so that MDP driver does
the appropriate settings to allow this process.
