hwc: enabled FBDC for compressed data buffers.
BZ: 164299
This is 3/4 patch for FBC/DC enabling.
updated RGB plane to support compressed data buffers.
Currently, FBC/FBDC only take effect on non framebuffer
layers since HDMI primary plane (sprite B) doesn't
support FBDC.

Miscellaneous optimization on HWC
BZ: 97852
1) new lockDataBuffer and unlockDataBuffer to avoid frequent memory allocation and de-allocation
2) move hotplug control and vsync control to HotplugEventObserver and VsyncEventObserver to make them self-contained
3) new event queue to handle hotplug event, video event and phone event
4) dynamic vsync source management can be easily disabled or enabled. (disabling it will cause UI hang)
5) eliminate using of "goto" design
6) make destructor virtual, not necessary for derived class but is a common practice
7) disable overlay use when video playback starts, to avoid potential scrambled RGB overlay
8) vsync status is committed only when it is scussefully enabled or disabled
9) fix memory leak (DataBuffer allocated but not released)
10) many other small improvements

Handle protected video playback.
BZ: 103301
This patch contains the following changes:
1) Define GraphicBuffer class and make it part of common library.
This class wraps buffer format and buffer usage as for now and provides
helper to check whether buffer is protected.
2) Avoid overhead of multiple data buffer creation during prepare, buffer is created
only once and attributes of buffer is stored internally for later use.
3) Ensure protected video is always rendered using harrdware overlay. IED needs to
be enabled when protected layer is received, a special hint is set in backbuffer
(OSTART_0Y) such that display controller can enable IED decryption during flip.
