We need to call commit on wfd even if in paused state so that pipes

When WFD is connected to 8x26
1) On Video transition, have 1 padding round if external connected.
Required to shift pipes across mixers.
2) Request DMA pipe always for FB on WFD.
Necessary for rotation + writeback
3) Disable non-worm-hole calcs on external (because of 2)
4) Disable action-safe calcs on external (because of 2)

In case of videos, do a fallback using 2 pipes per mixer at most.
This redraw will happen only once to reduce pipes from at most 4
to at most 2 and never draw again until there is an update.

With such varibles in hwc, it still leads to overlay giving out DMA pipes.

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.

- On suspend, SurfaceFlinger calls hwc_blank on primary and
external separately, inbetween these calls there might be a
update, which leads to acquiring overlay pipes for external
which will not be cleared and results in showing up stale
frame on external display
- This change clears all the overlay pipes used on every blank

This change adds support to MDP composition to use DMA pipes when
layer scaling is not needed. Also makes sure not to invoke
MDP rotator when DMA pipes are configured since MDP rotator will
expect both the DMA pipes to available for performing rotation.
In such cases, we let the first frame of rotated video frame to
fall back to FB.

-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.

Sometimes vsync would not be disabled before the display is
blanked.
This was due to the vsync disable ioctl being kicked off in a
thread different from the event control which surfaceflinger
called. So, while the calls from surfaceflinger are in order, the
order of execution wasn't always the same. Hence, making sure
ioctls are called in the same context to ensure order.
Also
- Make blanking/unblanking logs show the operation as a string.
- Add a debug property to dump vsync timestamps (needs framework
reboot)
- Remove a log which showed delay in reading vsync. This log was
unreliable when vsync is disabled and we're still reading from
the sysfs node.

Surfaceflinger does not send Blank/unblank event to hwc for virtual

that any pipes unset gets committed.

The earlier copybit solution involved blitting directly into
the SurfaceFlinger's framebuffer target. That solution involved
unnecessary framework changes and caused issues when the
framebuffer was being written to both by GL and copybit.
Update hwc_copybit to use our own buffers for this purpose.
We also make sure we display only the region we're interested in
so that unnecessary artifacts from previous blits do not show up
on the display. This way, we can avoid clearing the intermediate
buffers every frame.

Close acquireFenceFds always even in case of failures if a layer is either
OVERLAY or FRAMEBUFFER_TARGET to prevent leaks in case of failures.
The framework is *not* responsible for closing acquire fds, for layers

Android has scenarios where it calls HWC::prepare and HWC::set
without any application layers. In such cases, for power
optimization, user space avoids calling PLAY
(on FB - since there is no new content drawn) and COMMIT ioctls.
But we might have called UNSET on mdp pipes used for the previous
frame. As per the current MDP design, these freed pipes will not
be unstaged unless atleast a COMMIT ioctl is called on that mixer.

This change introduces hdmi pending state, where we allow
frames to fall back to FB, closing all MDP pipes.
Pipes could be used by primary (mixer 0) in which case moving
them to external (mixer 1) involves unsetting them and setting
them in the same round which is not recommended by the driver.
It will fall back to GPU till HDMI is configured on a connect
event.
