Adds the colorTransform field, which defines a vendor-specific color
transform (e.g., wide gamut, sRGB, etc.) to the DisplayInfo class, and
populates it from the HWC interface.

Adds code to track whether SurfaceFlinger has sent two frames to HWC in
the same vsync window. This can occur if one frame is delayed so far
it slips into the next window or just if one frame takes an abnormal
amount of time. If this occurs, it shows up as FrameMissed in systrace.
Also adds a property debug.sf.drop_missed_frames which, if set, tells
SurfaceFlinger to skip sending a frame to HWC (i.e., calling
prepare/set) when we detect this condition, which can help prevent
backpressure from the HWC implementation.

This allows changes to the SECURE flag to propagate down to
Layers in SurfaceFlinger so that WindowManager can change it on the fly

Once HWC is created, it could use any of the provided hooks, which
could lead to a crash if the EventThread (handler) isn't initialized
prior to creating HWC.

Validate the display binder by adding a NULL check in getDisplayConfigs.
This will prevent a false match if the caller queries the display
configs for an inactive display (whose binder is NULL by default).
Without this change we might end up attempting to index the display
config array, which is unpopulated for inactive displays, and this will
result in a crash. (See getDisplayInfo in SurfaceComposerClient.cpp for
an example of this scenario)

Early during the boot, before activity manager is ready to handle

(cherry picked from commit 3bfe51d790)
In cases where SurfaceFlinger is applying a color matrix (usually for
accessibility features), we previously would perform a render-to-
texture for the initial composition, and then apply the matrix during
a copy to the framebuffer. This changes that behavior to just apply the
matrix during composition without a render-to-texture pass.
This may result in a perceived change of the image in cases with alpha
blending, since the blending is performed at a different stage of the
pipeline and the system effectively performs non-linear blends.
However, neither this nor the prior render-to-texture pass is strictly
correct in that regard, and this approach is less error-prone and
likely faster.

This modifies EventThread such that its phase offsets for both
Choreographer and SurfaceFlinger may be modified at runtime. It also
plumbs this functionality up to the SurfaceFlinger debug interface so
that it is possible to rapidly test different offsets without
restarting the framework.

Adds a --static-screen option to dumpsys SurfaceFlinger, which
displays screen-on time broken down by the time between the prior
frame and the current frame. An example dump looks like this:
$ adb shell dumpsys SurfaceFlinger --static-screen
Static screen stats:
< 1 frames: 12.235 s (3.5%)
< 2 frames: 29.898 s (8.7%)
< 3 frames: 15.370 s (4.4%)
< 4 frames: 13.103 s (3.8%)
< 5 frames: 15.780 s (4.6%)
< 6 frames: 2.022 s (0.6%)
< 7 frames: 0.201 s (0.1%)
7+ frames: 256.887 s (74.4%)
The buckets are exclusive, so '< 3 frames' covers the interval
[2, 3) frames

Rather than trying to acquire the state lock without waiting three
times at 1 second intervals in SurfaceFlinger::dump(), just try to
acquire the lock once with a 1 second timeout. Avoids spurious mutex
acquire failures that lead to flaky

"Do less work when using PTS" broke the invalidate path up from HWC
to SurfaceFlinger. When HWC would signal an invalidate, SurfaceFinger
would wake up, see no new buffers, and go back to sleep. This is fine,
except when the invalidate is a result of an HDMI hotplug, in which
case the screen remains blank. This change makes that functionality
work again.

Currently, SurfaceFlinger is very dumb about how it handles buffer
updates at less than 60fps. If there is a new frame pending, but its
timestamp says not to present it until later SurfaceFlinger will wake
up every vsync until it is time to present it. Even worse, if
SurfaceFlinger has woken up but nothing has changed, it still goes
through the entire composition process.
This change (mostly) fixes that inefficiency. SurfaceFlinger will
still wake up every refresh period while there is a new frame
pending, but if there is no work to do, it will almost immediately go
back to sleep.

This change watches for a MAX_VIRTUAL_DISPLAY_DIMENSION value, which
will be set (if necessary) in BoardConfig.mk. If the value is set,
any virtual displays that have a width or a height greater than that
dimension will bypass the hardware composer HAL and be handled only
by SurfaceFlinger.
