Unlock overlay buffers before going to suspend

In video playback through overlay, it is observed that, during
suspend/resume, genlock TIMEOUT errors are seen at the component
level.

drawLayerUsingOverlay() function locks buffers, but doesn't unlock
them, before going to suspend, making the genlock_lock_buffer calls
from video component to fail.

Unlock any overlay buffers before going to suspend.

libhwcomposer: Implement register_proc in HWC

register_proc in HWC is used by SurfaceFlinger to register
callback functions with HWC. This can be used by HWC to invoke
SurfaceFlinger functions. Currently invalidate is the only function
registerd and can be used by HWC to trigger a screen re-draw.

libhwcomposer: Implement idletimeout fallback for MDP composition .

Background: On MDP compositon, MDP keeps reading contents from the
pipes even on Idle Screen i.e. even when HWC is not queueing any new
buffers to MDP. Above data traffic leads to high power consumption.

Implementation: This change introduces a timer in HWC which will
timeout if there are no updates in bypass composition path for
the period specified via debug.bypass.idletime. Also SurfaceFlinger
will be notified to redraw the current frame which will be composed
into FB.

liboverlay: set correct flags for external display channel

When external display is connected during video playback, the

liboverlay: Remove evening-out of layer destination coords.

Evening-out of layer destination coords causes a noticeable up & down
shift in the screen when video layer drawing switches between Overlay
and GPU. This is most easily observed during video playback or pause,
when a UI layer (like Menu) is displayed / hidden. Remove evening-out
of layer destination coords to fix the video layer "twitching" issue.

Fix secure flags value in overlay.

Remove the member "secure" from overlay_buf_info.
This member was used to indicate secure content and this info was
later extracted out into existing flags. Now we use the same flags,
right from hwc to mark secure content.

The member above had junk value, since it wasnt initialized.
This caused, normal videos to fail with IOMMU. Removal of the member and
marking the existing flags fixes this.

YUV layer updates during animation and popups.

-- During animation, if yuv layer is marked skip close overlay channels.
   But if HDMI is connected, let them remain open, and send data.

-- During popups on paused video, if the layer above it is skip,
   let the video layer be displayed via overlay.

-- Fix MDP pipe closing mechanism for yuv content.

-- Synchronize notification to gralloc with actual video channel status.
