SF: Block gpu rendering for virtual display widevine level3

In MPD3 we are using the widevine level3 for secure content
display. And this should applicable only for primary display
not for screen shot or screen recording.

single video session

Display: Add swaprect feature for MDP composition.

Add swaprect feature for MDP composition.
SwapRect is a SurfaceFlinger feature for selective composition
of only thedirty region.
* Existing SF does copying of the complete layer for every
 layer (in effect the full screen) whether or not the layer's
 information has changed (dirty region).
This is very inefficient use of compositing hardware (MDP/GPU).
* At the app level, we're doing dirty region rendering (App only
renders what is changed) using the feature "Dirty Region Rendering".
So, at the app level we know what has changed (dirty region) per
 layer. But SurfaceFlinger doesn't know this info and hence it's
 not able to use dirty region for selective composition and ends up
 compositing full screen.
* For SurfaceFlinger to composite only the dirty region
   1. It needs to know the dirty region (This needs to be passed
      down from the app)
   2. It needs to pass this info to the actual compositing hardware
     (MDP / GPU) so that the hw can do selective composition
* SWAPRECT feature needs to implement 1 & 2.
* 1 is common for all composition types whereas 2 is different
 for each composition type
This change implements 2 for MDP composition
* We've also added strong checks in the feature to make sure the
 feature kicks in only for the UX scenario's where performance
 improvement is expected and no functionality issue would arise.
To enable MDP Swaprect, setprop debug.sf.swaprect 1 and restart
framework.

sf: Enable swaprect optimization by default only on QCOMs

 * This is confirmed to cause problems at least on i9500.
 * Only enable it by default on QCOMs, other devices can opt
   in using the system property.

SF: Add flag for swaprect status in HAL

We need to check in HAL whether swap rect
is enable or disable to calculate wormhole region.

SurfaceFlinger: Change to support framebuffer flip for 2D blitters

- Surfaceflinger does not flip framebuffers when there are
  no layers marked for HWC_FRAMEBUFFER
- This change checks for the HWC_BLIT flag and will request a flip
  to a new FB_TARGET buffer even if there are no FRAMEBUFFER layers

Display: Define new composition type for blit composition

This change defines a new flag 'hasBlitComp' to identify
blit composition. This flag is used to enable the swap rect
feature for blit composition cases.

Revert "Add sessionId metadata with every buffer queued through Surface"

This reverts commit 85743373ed7d4eb6cb58412bda6c74f9ee29f06f.
This change is no longer needed

surfaceflinger: Conditional compilation for swaprect feature

 * Since this now calls into the HAL, we can only support it on
   devices which use the new version.

Do not just silently fail if surface creation fails

Some apps do not check if they actually got a surface (e.g. bootanimation)
So this helps the track crashes down to the cause.
