hwc: cache layers on framebuffer

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.

hwc: Add support for faking vsync

Can be set for debugging, valgrind, board bringup etc.
Also - we fail reading the sysfs vsync, we fall back and fake it.

hwc/overlay: Dynamic pipe tracking.

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.

hwc: Use number of app layers from the hwc context.

Current frame count is not valid in cases where MDP
composition is not doable. This could lead to clearing
the flags for the wrong number of layers.

hwc: Avoid MDP composition with alpha scaling

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.

merge in jb-mr1.1-release history after reset to jb-mr1.1-dev
Fix two trivial bugs found by gcc 4.7.

1) external.cpp: ext_commit.flags is uninitialized.
2) hwc_mdpcomp.cpp: signed int compared against another signed int
   which is unnecessarily casted to unsigned.
