Add a client interface which interfaces with hwc.
qservice upon receiving IPC, provides a callback notification to the qclient
which does appropriate stuff in hwc.
In future, qservice can safely be even made a separate process with no changes
to exisiting code. This was not true earlier owing to the hwc pointer held by
qservice forcing it to be in the same process that hwc is in.

This change introduces the following changes:
- Frames having 2 yuv layer can be bypassed
- if not handled by MDP comp, video path will not
handle any such frames and will be FB rendered

- Add CopybitEngine to hwc_context
- draw the layer on the HWC_FRAMEBUFFER_TARGET using
copybit(c2d) if it qualifies for C2D composition.
- use fence returned from the copybit during c2d
composition

This change introduces hdmi pending state, where we allow
frames to fall back to FB, closing all MDP pipes.
Pipes could be used by primary (mixer 0) in which case moving
them to external (mixer 1) involves unsetting them and setting
them in the same round which is not recommended by the driver.
It will fall back to GPU till HDMI is configured on a connect
event.

MDP4 supports scaling with alpha, only in RGB pipes.
In some cases this scaling happened with video pipes.
We now fall back to GLES composition for layers that have
alpha and need scaling.

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.

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.

* 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.

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.
