Add a BWC policy manager that decides if BWC needs to be disabled on
certain conditions.
These conditions are statically determined. BWC might get used and
still fail (or cause failure of subsequent pipe requests) if SMP
blocks are not sufficient.

In scaling check, consider out of bounds layers, apply trim
and then decide if scaling is necessary or not.

Since configRotator gets called from FBUpdate for non-YUV layer,
check for YUV formats is required.

These include constrained targets, with external connected which could
lead to a scarcity of pipes. Furthermore owing to a scarcity of writeback
interfaces, even if pipes are available, we may not be able to still
use rotator.

If configRotator fails, reset usage & allocation bits on all pipes
for the given display to make them available for the current draw
cycle. It is required because if external is connected and Rotator
commit() on Video fails, all pipes which were picked-up by primary
are not available for FB update, hence it runs out of pipes.

- When primary is animating, the animation should not be
shown on the external display.
- Mark all app layers as HWC_OVERLAY on external during
animation so that SF wont compose it on FB.

- The required orientation on External can be set using the
properyt sys.ext_orientation.
- Values can be HAL_TRANSFORM_ROT_90, HAL_TRANSFORM_ROT_270
- According to the value set, the FB_TARGET for External will
be rotated and positioned as per aspect ratio on Ext
- For YUV(video layer) it just calculates the position, as the
rotation should be the source orientation
- This feature is supported only for low resolution panel.

If there are any EXTERNAL_ONLY layers present in the list, mark
them as HWC_OVERLAY such that SF does not compose and in hwc_set
post that layer to Ext display, ignore other layers

- This adds support for Bandwidth Compression.
- If MDSS supports BWC, then we set BWC flags
to both Rotator(encode) and overlay(decode)

Introduce a padding round between the DMA line and block modes.
Do this based on whether DMA is actually being used, when block mode
is first requested.
This relieves the driver of doing an UNSET ahead of vsync which could
cause blinks in all such transition scenarios.
This approach should lead to smooth transitions for multiple targets
with the exception of secure videos, where there could be a blink in
any of the different approaches we use.

It is more probable that end user always use same TV to connect.
Hence make the action safe property persist, so that it is
persistent across reboot
Also, change property to sys. from hw. so that hwc can write

Add support for tracking the mode in which DMA is being used in overlay.
Remove unnecessary tracking variables, and their set,reset inconsistency.
With such varibles in hwc, it still leads to overlay giving out DMA pipes.
Make overlay as the single tracking place.

Log a frame-by-frame succession of HWComposer layers' data and write

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.

With this change we are moving MDP composition from all-or-nothing
implementation to mixed mode implementation where layers can
partially be composited through MDP and while rest of the layers are
composed / cached in framebuffer.
- Mixed mode design is based on layer caching
- Mixed mode path is configured only when non-bypassing
layers are cached.
- Never allow mixed mode when FB needs to be udpated.
- If we cannot bypass all MDP comp marked layers, bail
out completely.

In some cases it is seen that we receive a NULL handle on
suspend/resume. One such test case is open browser, suspend
device, resume device, unlock screen. Since we rely on the handle
to get the format, make sure it is not null.
