Display configs for external displays are stored in the framework
everytime we receive a hot plug to connect. However, since the
configs are not cleared on disconnect, framework will just assume
that the configs are valid. This does not work for use cases when
you connect/disconnect external displays with different resolutions.
e.g. 1080p to 4K and vice-versa
With this change we clear the display configs and repopulate when
we receive a hot plug to connect.

By not committing the results of composition for empty frames, we
avoid spitting out series of black frames for virtual displays that
don't have visible layers. We still draw one black frame when going
from having layers to not having any. In particular, this avoids
having a series of empty frames due to re-compositing the primary
display in the period between creating the virtual display and adding
layers to it.

Do not wait for the screen capture to complete within surface flinger,
instead pass a sync point back with the captured gralloc buffer.

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.

- Adds a sticky transform field that can be set from a
SurfaceFlinger client Surface. This transform is
added to any transform applied to the Surface.

The existing code worked in practice, but wasn't quite correct in
theory and relied on implementation details of other code. It's still
somewhat unusual and subtle, but now is correct-in-theory (I believe)
and a little better documented.

This is necessary to use C11/C++11 stdlib atomics, which the next
change will do. This change also fixes a couple bits of syntax that
both GCC and Clang refuse to compile in -std=c++11 mode.

This forces all SurfaceFlinger sources to be recompiled when the
Makefile changes; that's overkill sometimes but makes sure everything
gets recompiled when compile options (or similar) changes.

Removes the dependency on default constructor parameters for

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).

VSYNC power hints are now sent via binder to IPowerManager.
SurfaceFlinger no longer loads a second copy of the PowerHAL.
VSYNC power hints are sent in batches and not on per frame basis.

This replaces the previous low-power mode experiment, which
discarded refresh events, with a new experiment that alters
the refresh period.
(see also I2849e5ea335c0d2509fea1c315392bce7f20451d )
The feature is enabled by specifying a nonzero value for the
"refresh skip count", which indicates the number of periods
to skip. For example, the command:
adb shell service call SurfaceFlinger 1016 i32 1
sets a skip count of '1', yielding a 30Hz refresh rate on a device
with a 60Hz display. Changing the last value to '2' would set the
refresh to 20Hz. '0' returns to the default behavior.

If app and SF events aren't using phase offsets, we don't need
to maintain the DispSync model. We just turn hardware VSYNC on
whenever something wants to draw. This avoids some edge cases
where we were doing too much resync work.
Also, updated the systrace output. The "VsyncOn" line was a
combination of SF and app event threads, and would occasionally
be very weird. Removed VsyncOn, renamed VSYNC to VSYNC-app,
and added VSYNC-sf.
Also, added more details to the --dispsync dumpsys output.
Also, renamed global constants to not look like local variables.

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.
