This change fixes a bug that caused an extra frame of latency when enabling
vsync event callbacks in DispSync. The bug was related to the logic that
prevents the two events from firing with very little time between them due to
updates to the vsync model.

Continuing to send the last-rendered framebuffer to HWC on subsequent
frames allows the HWC to read partially-composed regions that haven't
changed, instead of re-composing from scratch.

We were already making sure the HWComposer class had the handle before
prepare, but it wasn't passing the handle along to HWC as intended.

If the virtual display surface is being consumed by the CPU, it can't
be allowed with HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED since there is
no way for the CPU consumer to find out what format gralloc chose. So
for CPU-consumer surfaces, just use the BufferQueue's default format,
which can be set by the consumer.
A better but more invasive change would be to let the consumer require
a certain format (or set of formats?), and disallow the producer from
requesting a different format.

i) Emulate Flush for AOSP Fusion Sesnsors on newer HALs that support batching.
ii) Early return if there are no events for the current SensorEventConnection.

1. When alloc or realloc failed in the function SharedBuffer::editResize,
it would return a NULL pointer, then mStorage would update to be 1 by
SharedBuffer::data() if no pointer check here, which is an obviously
wrong address, and would cause corruption when used it e.g. in capacity().
So add the pointer check here for the return value of SharedBuffer::editResize,
if it's NULL do not use it to update mStorage, to avoid the value of mStorage
polluted.
2. when alloc or realloc falied in _grow & _shrink function, mStorage keep
the original value, so mCount should not be updated here.
Otherwise, mStorage might be 0 but mCount>0, so a corruption would happend
when it try to delete items from the Vector since mCount>0.

When resampling is disabled, it's currently possible to consume
touches after the current frame time. This breaks some guarantees and
could cause unexpected behaviors.

When a BufferQueue producer disconnects and reconnects, we retain
the previously-queued buffers but empty the slots. This allows
the number of queued buffers to grow without limit. The low-memory
killer does not approve.

When this boardconfig is defined, even when all virtual display
composition is done by GLES, the HWC will be forced to copy from the
GLES framebuffer to the output buffer. On some hardware this allows
HWC to do format conversions that would otherwise have to be done by
the consumer, with worse power and/or performance.

When GLES isn't writing to the output buffer directly, request an
implementation-defined format with minimal usage flags, leaving the
format choice up to gralloc. On some hardware this allows HWC to do
format conversions during composition that would otherwise need to be
done (with worse power and/or performance) by the consumer.

* commit 'dacd4159631865da1a02203fe5fa7c5f1339cda9':
Change API from flush(handle) to flush(). Call flush on all active sensors in the given SensorEventConnection.
Eliminate latency when resampling is disabled
Fix blank / partial screenshots
Set the outbuf acquire fence after we actually have it.
only clear FB when asked for the opaque layer
Treat composition frames with no layers as using GLES composition

This change allows SurfaceFlinger to run at a different vsync phase offset from
that used by external listeners.
