Reset compositionType to HWC_FRAMEBUFFER before calling prepare()

Honor the documentation. this broke in JB-MR1.

fix an out-of-bounds memory access

in this particular case, this OOB is always harmless
(and that's why it didn't get fixed from MR1), however,
it interfers with valgrind debugging.

workaround: don't reset compositionType to HWC_FRAMEBUFFER [DO NOT MERGE]

make transform hint multi-display aware

if a layer is not mirrored, we now use its display
as the source for the transfrom hint calculation
instead of always using the default (main) display.

this change does two thing:
1) we make updateTransformHint take a DisplayDevice
   as a parameter instead of hard-coding the
   main display.

2) each time we do a transaction that could change
   the hint, we go through all layers and
   figure out which display should be used for their
   transform hint.

DO NOT MERGE GraphicBufferAllocator: make frees async

This change makes GraphicBufferAllocator::free queue a job to another thread to
perform the actual free operation.  This prevents potentially slow free
operations from blocking rendering.

[DO NOT MERGE] GraphicBufferAllocator: stall alloc for async frees

This change makes GraphicBufferAllocator::alloc wait for pending async frees to
complete before attempting to allocate a gralloc buffer if there are more than
8 pending async frees.
