Synchronization is needed,to make sure, read() is not called
by hwcVsyncThread when VSYNC is disabled.
Otherwise in usecases, where display is OFF, and still some
tasks keep running in the background; SurfaceFlinger hogs
CPU.

* Read sysfs entries, to get vsync timestamp from kernel.
* External display continues to use in ueventThread.
* A new thread, vsyncThread is created to read and send vsync
timestamps to HAL.
* Disable H/W VSYNC for MDP 5.x targets until kernel changes are
complete.

- sourceTransform in the hwc_layer_t has the source buffer transform,
use this transform for external display.
- This helps in showing videos with source orientation properly on the
external display
- Remove unsed flag FINAL_TRANSFORM_MASK

Secure content can not be displayed unless in an overlay. Since
getLayerStats marks all layers under the skip layer for framebuffer
composition, when there is a skip layer on top of protected content,
the protected content disappears since surfaceflinger doesn't draw
protected layers.

Draw sequence in hwc_set
--eglSwapBuffers
--wait for fb_post. Its ok to draw to External only at this point.
--draw to external | Parallel with PAN
--commit to external | Parallel with PAN
--wait for pan (happening in fb_post) to finish.
Call MSMFB_OVERLAY_SET ioctl only when params change.
These thing together ensure a correct sequence and should fix tearing and
stuttering, the latter assuming there are no other display pipeline delays.

This change
1) implements MDP Composition upto 3 layers
2) adds invalidator support to fall back to FB
composition during idle screen condition.
