* 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.

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.

* Limit the number of rotator sessions to 4 both in
LayerRotMap and RotMgr structures
* Make use of MDPVersion getter fuctions to check
for maxMixerWidth and maxDownScale supported by MDP

Change max rotator sessions to 4, since we could support upto
those many.
Change error log to warning log on reaching beyond max rotator
sessions, since its not really an error, but flagging it as one
raises false positives in testing filters.

Remove all klockwork warnings and errors for libgralloc,
libhwcomposer, liboverlay, libqdutils, libqservice, libvirtual,
libexternal libraries to avoid buffer overflow and memory leaks.

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.

Earlier, on configuration errors, we simply drained the fences held
by current rotator objects and went to GPU comp. The rotator objects
were deleted in the subsequent rounds, if they remained unused.
If we don't use GPU comp on failure but use other strategies, then we
need to mark the rotator objects for a display for reuse, so that
other strategies can use them.
Also any failure resets on overlay or rotator need to happen from
functions that call configuration helpers rather than the helper
themselves. Leaving cleanup to black-box helpers is not desirable.

When a rotator or mdp configuration for a display fails, reset the
layer-to-rotator mappings for that display and reset the release
fences for the rotator objects used for that display.
Note: The rotator itself is offline and not tied to any mixer. It is
from the mappings that we deduce which rotator object was used for
layers of which display. Also we don't delete rotator objects held
for a specific display, since during stability runs, failures could
repeat each round and we end up allocating and deallocating memory
unnecessarily. The rotator objects will be deleted automatically
when not required anymore.

Add dumpsys information from writeback data structure.

Enable sync-pt for rotator on B-family. The already existing
MSMFB_BUF_SYNC ioctl is used, with an extra member for session_id
from rotator.
Change-Id: Ib0ef6b1bc5cf1e6437090a217d7f731a3440f84b
Implement sync for rotator.
If a buffer is rotated, it can be used by producer soon after
rotation (and it wont have to wait until vsync).
Mdp waits for the rotator buffer's release fence to signal
to start display.
Hwc waits for previous access to rotator buffer by MDP to finish
before using it

-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.

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.

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.
