reduce PB size from 2MB to 512KB

this allows us to enable h/w acceleration on low-end
devices while keeping memory usage down.

sf:  Add dirtyRect information to SF dumpsys

Display dirtyRect information generated for each layer in
SurfaceFlinger Dumpsys.

sf: Use Dirty Rect optimization in "Show Surface Updates" setting

When "Show Surface Updates" setting is ON in developer options, flash the
updating part (union dirty rect) instead of full layers when
GPU Tiled DR optimization is ON.

SF: Modify logic to handle "transparent Region" for displayFrame

sourceCrop and displayFrame calculations according to "transparent Region"
are not synchronized. Because of this mismatch scaling is introduced,
causing corruption in UI. To avoid this scaling, map displayFrame to
sourceCrop, apply reduce and remap result to displayFrame.

Init display orientation according to panel orientation

   - Initialize the display default orientation to panel orientation.
   - honor the panel orientation only after the end of boot animation
     or the new orientation is as same as panel orientation.

SF: Ensure boot animation always appears in panel orientation

Ensure that boot animation is always shown in panel
orientation.

surfaceflinger: Track the last surfaceview frame for latency dumps

When measuring GL latency with dumpsys, it's possible to hit a
race condition if the hardware is fast enough to complete rendering
the test cycle before the latency dump is requested, since it only
matches the latency for live layers (unless it's an animation. See
change I8bded1ea08a4cddefef0aa955401052bb9107c90)

So always save a reference to the last rendered SurfaceView frame,
and dump its values if there isn't an active one.
