This change extends MDP composition to support

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.

MDP doesn't like out-of-screen-bounds parameters. So based on the position of
the layer, we adjust the portion of layer the MDP should pick.
However, this did not factor in orientation, so far. This patch does that and
allows panning to work in other orientations, without having to use GPU.
