This change extends MDP composition to support
upto 4 layers by making border fill as base pipe and
using all MDP h/w pipes in overlay mode.

Remove state based pipe handling and make pipes tracked dynamically.
Add the configStart, configDone, nextPipe availablePipes APIs.
Remove setState API.
-configStart marks all pipes available.
-configDone garbage-collects unused pipe objects.
-nextPipe returns the index of next available pipe and create a corresponding
pipe object if not present
-availablePipes returns total of "unallocated" pipes. (Pipes could be allocated
but unused)
Changes in hwc adapt to the new overlay APIs.
Compile out MDP comp.
Remove unused files in overlay and hwc.
Update licenses.

In the cases where all the layers that are marked as HWC_FRAMEBUFFER did not
change, we can mark them as HWC_OVERLAY since their contents are already on the
framebuffer and do not need any additional processing.
This optimization shows power improvement for video playback.

Cleanup overlay for external from the draw thread. If done from the uevent
thread, its possible that the object being used by draw thread is deleted by
uevent thread.
This also removes unnecessary side-effects where libexternal sets states in
hwc, whereas, it could be set from hwc itself. There should be no need for
libexternal to modify states in hwc.

We are seeing errors where a device's hwcVsyncThread is not present for some
reason. The surface flinger has not crashed, so either the thread never got
created, or it exited withouth throwing an error. This patch adds some more
verbose on-error logging to the HWC as an attempt to verify the theory that the
thread does not get created, or fails in pthread_create. While we're at it, we
add the same logging at pthread_create() for hwcUeventThread, as well.
Also, replace the lseek()+read() with a pread() combo in the vsync thread.

* Read sysfs entries to get vsync timestamp from kernel.
* External display continues to use uevents for hotplug events
* 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.
* Synchronization is needed to make sure read() is not called
by hwcVsyncThread when VSYNC is disabled.

Call sync before draw since draw could use rotator which reads out of the
buffer. For that to happen cleanly, the buffer should not be in use. Calling
sync before draw makes sure, the buffer is free to be used.
[TEMP]
Enable rotator for external video, since sync-pt is not used for external yet.

--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.
