bd3bdc6d03 hwc/overlay: Implement rotator caching
* A non-updating layer requiring rotation, can make use of
the older rotator buffer written when the layer got first
updated, rather than invoking a new rotator cycle.

* A rotator play is avoided in cases where incoming layer
buffer fd, offset, whf, src-rect, dst-rect, etc are similar
to that of the previous input layer to the rotator.

* For ex: In a usecase where video layer updates happen at
30fps and all other asynchrous UI updates happen at 60fps,
instead of the traditional 60 calls of rotator play per sec,
we now do only 30 thereby saving rotator bandwidth.

* Property "debug.rotcache.disable" can be used to disable
this feature.

c46cf9d26b overlay: Add support for rotator downscale
Add support for rotator downscale. This is enabled from 8994 onwards
Constraints:
--Downscale should be a power of 2, max upto 32
--Both directions should have equal downscale
--{src_w, src_h} mod downscale = 0
--No BWC
--No Interlaced video support

The rotator's destination rect is modified to reflect the presence of
downscale. Any downscale calcs should be done only after adjusting
crop to meet rotator's requirements.

Smaller downscale is used if we need to chop off any more than 1
line or pixel.

8ec9b5eda4 hwc/overlay: Get rot dest dimensions instead of manipulating source
Currently for Mdss rotator we manipulate the layer buffer dimensions
to be equal to what rotator's destination dimensions would be, so that
these could be fed to MDP. Instead, this patch introduces APIs in
rotator so that hwc can directly query destination crop, width, height,
format from rotator.

This also simplifies the updateSource() and configRotator() helpers.

912c94833a overlay: rotator: Remove previous allocation for a session
When ION was not ref counted, we needed to maintain the previous
session memory until the new one was taken by MDP. ION being
ref counted now, it is not necessary to maintain previous memory
allocation.

80fc1f95f0 hwc/overlay: Set crop rectangle for MDSS Rotator.
Since MDSS rotator will crop, the crop rectangle for overlay
will always start from (0,0).

ae61b2b2c3 hwc: Fix dumpsys crash
In extreme cases, when all pipes are used, the buffer is insufficient.
Reduce logging by striping off unnecessary bytes.

d1a2278d97 overlay: Swap flips on 90 only for older mdp version.
Older mdp rotator does 90 first and flip next,
forcing HAL to swap flips, in presence of 90.

Newer mdp does flip first and 90 next, owing to DMA pipe.
(Also similar to GPU flip handling). So we can pass flips as-is.

acf102021a hwc/overlay: Video on 4k2k external, 4k2k rotation.
-Add support for Video via overlay on 4k2k external panel.
-Add support for rotating videos on 4k2k panels. We use
pre-rotation in hwc to rotate a video into a single buffer,
irrespective of panel size. Then this buffer is fed to MDP.
Rotator objects are managed by the new RotMgr.
-Cleaup mdpcomp and overlay.

4ca8f3aa9a display: Do not align down input rotator src height
Aligning down the input rotator source height value introduces
green line in the output of the rotator. Remove aligning down the
input rotator source height for YV12 format.
For 1/8th downscale use aligndown instead of alignup.

fc3652f2c7 overlay: Fix rotator output buffer size.
Fix rotator output buffer size for mdp and mdss rotators.
Output size is based on rotated width & height.
Output format can be different than source format.
It could be same if using mdss rot or using fastyuv mode in mdp rot.
Deprecate the static mapping of rotator input and output formats.
Driver will be responsible for correctly populating the dest format that its
wishes to use.

23f69b29e4 liboverlay: Set mdp src format as rotator output format.
* Set mdp source format as rotator output format
rather than determine it from a fixed mapping of
input/output formats.

* This is needed since for the same input format
to rotator, fastyuv mode if enabled may result in
a different output format than the one if the mode
is not enabled.

* Do the inline optimization for rotator where possible

288f8c7e25 liboverlay: Rotator-assisted MDP downscaling of videos.
Engage the rotator to assist MDP in performing video downscale for
primary and external. This saves bandwidth and avoids causing the
driver to make too many panel mode switches between BLT (writeback)
and non-BLT (direct) modes.

758bfc5b50 hwc/overlay: Dynamic pipe tracking.
Remove state based pipe handling and make pipes tracked dynamically.
Add the configStart, configDone, nextPipe availablePipes APIs.
Remove setState API.

-configStart marks all pipes available.
-configDone garbage-collects unused pipe objects.
-nextPipe returns the index of next available pipe and create a corresponding
pipe object if not present
-availablePipes returns total of "unallocated" pipes. (Pipes could be allocated
but unused)

Changes in hwc adapt to the new overlay APIs.
Compile out MDP comp.
Remove unused files in overlay and hwc.
Update licenses.
