On one device there is a bug, not yet root-caused, that causes fence
fds to not make it across binder from producer to consumer in the
IGraphicBufferProducer::queueBuffer call. Rather than returning an
error, which the producer typically treats as a fatal error, this
change allows the buffer to be queued with no fence. This avoids an
application crash at the risk of (likely single-frame) visible
corruption.

Previously it was possible to have the driver's eglTerminate called beofre
eglDestroyImageKHR in GLConsumer. This was because we didn't increment the
refcount for the lifetime of the image. This could lead to a crash or a deadlock
when multiple threads called terminate and destroy simultaneously.

Throttling was previously controlled by a combination of the
driver and the number of buffers in the queue. This patch makes
a more consistent trade-off, which allows two GPU frames pending
but not three. More buffering could improve throughput in the
case of varying frame times, but this also increases latency.

has been previously added or not.

when one-shot sensors trigger.
ii) Maintain a mapping between flush_complete_events and

iii) Remove all references to 1_1 and 1_2 HALs.
iv) Dynamically allocate sensor_event buffers in SensorService main
threadLoop.

If a display is terminated and then initialized, we can't detect
this using the display itself (it has the same value), but all
EglImages still become invalid for the display. This patch detects
this during image binding and forces creation of a new EglImage.

Modify SurfaceFlinger to use VirtualDisplaySurface in all cases when a virtual
display is used. Add functionality in VirtualDisplaySurface to resize the
buffers aquired in the QueueBufferOutput. Add transaction support in
SurfaceFlinger for resize. Add the modification of the size in DisplayDevice.

Commit 78014f32da introduced a bug that
made us pre-allocate buffers into the last available free slots instead
of the first available ones. This in turn caused more re-allocations,
and possibly triggered driver bugs.

BufferQueueProducer::allocateBuffers used to keep the BufferQueueCore
mutex while doing the buffer allocation, which would cause the consumer
(which also needs the mutex) to block if the allocation takes a long
time.
Instead, release the mutex while doing the allocation, and grab it again
before filling the slots. Keep a bool state and a condvar to prevent
other producers from trying to allocate the slots while the mutex is
released.

(cherry picked from commit ea96044470)
In most cases, EGLImages can be created one-to-one with graphic
buffers in slots, but that was difficult due to some special
cases:
- ReleaseTexImage binds a custom 'unslotted' debug image.
- When all slots are freed, we still need to hang on to one.
These cases were handled by keeping an additional reference to
the 'current' buffer (mCurrentTextureBuf), but we would create
new images since we can't reference count them in the same way.
This patch uses the same semantics, except that it reference
counts the image (an EglImage wrapper class) rather than just
buffer. The wrapper class also detects the cases when we need
a new EGLImage, and only creates them in those rare cases.

This adds an allocateBuffers method to BufferQueue, which instructs
it to allocate up to the maximum number of buffers allowed by the
current configuration. The goal is that this method can be called
ahead of render time, which will prevent dequeueBuffers from blocking
in allocation and inducing jank.
This interface is also plumbed up to the native Surface (and, in
another change, up to the Java Surface and ThreadedRenderer).

We replace the blank/unblank calls in surfaceFlinger with a more generic
setPowerMode() routine.
Some displays support different power modes (for example, with reduced
color palettes). Depending on the use case we should be able to toggle
these modes, so as to achieve incremental power savings.
Initially, three power modes will be supported:
- HWC_POWER_MODE_OFF
- HWC_POWER_MODE_DOZE
- HWC_POWER_MODE_NORMAL
HWC_POWER_MODE_OFF will correspond to blanking the display, while
HWC_POWER_MODE_NORMAL will correspond to unblanking. HWC_POWER_MODE_DOZE
will put the display into a low power setting, if it is supported in
hardware.
If such a low power mode is not supported, it should be treated as a
call to set the mode to HWC_POWER_MODE_NORMAL.
As a consequence of adding the mPowerMode field, the mScreenAcquired is
no longer required, and thus references to it are removed and replaced
equivalent references to mPowerMode.
We also add the glue code to connect the services invocation of setting
a power mode and the HAL implementation in HWComposer.

Write string lengths as uint32_t so that their width is
the same on 32 and 64 bit processes.
Note that this fixes another bug as a side effect; getFlattenedSize
was assuming that sizeof(uint32_t) == sizeof(size_t).
