Avoid ov set failures in rapid wfd pause/resume

* Avoid overlay set failures on receiving rapid wfd
pause/resume events.

* Go for videoOnlyComposition when isConfiguring is
set for external/virtual display and secure video
playback is happening instead of falling back to GPU
for composition.

* When external/virtual display is in pause state
and secure playback is happening, go for
videoOnlyComposition instead of full/partial MDP
compostion since the pipes connected to external mixer
will take atleast two vsync cycles to get unset.

* When requesting for an overlay pipe from pipebook,
give preference to the pipe which has already been
allocated to the required LayerMixer in the previous
round.

* Sometimes displayhal receives consecutive wfd-pauses
or wfd-resumes. Add a sanity check to avoid handling
unnecessary wfd pause/resume

Fixing array size to hold fence fd to count of render
buffers used in copybit, and use it to store
fence of corresponding render buffer at the index.

Initial msm8x64 memory tracker HAL

Reads memory info from kgsl to track unaccounted for GL and ION
memory.  Right now it has to parse every allocation and then
cross-reference it against /proc/pid/smaps.  It would be faster
to modify the kgsl driver to keep counters that could just be
read directly.

Donot compose layers if external is in pause state

* Donot compose external/virtual layer-list when
when external/virtual is in pause state.
* Marking the layers for GPU composition when external/virtual
is in pause state would update FB_TARGET layer which inturn would
affect partial mdpcomp after resume.
