Validate the previous overlay and bypass handles before unlocking
the buffers. The reason for doing this, is that in certain use cases,
after the previous handles are stored, the buffer gets destroyed and the
handle is now invalid. The HWC however doesn't know that the handle is
invalid and tries to unlock the handle, resulting in a failure.

Since composition bypass uses MDP overlays, which
need physically contiguous memory, we cannot use
bypass in cases where the buffers are using ashmem
or other virtual memory. Hence, avoid bypass in
such cases.

Synchronize turning off of composition bypass with display,
so that close happens only after FB content is displayed.
This fixes blinks observed when bypass needs to be turned off,
for reasons other than video content.

Add libgenlock which is a cross-process buffer locking API. libgenlock
provides the ability to create, attach, release locks. It also provides
a mechanism to lock and unlock buffers for read/write purposes.
