procrank is a setuid binary which only exists on userdebug/eng
builds. Instead of executing the setuid binary, run the binary using
the su command. This eliminates one more setuid binary, and allows
the tightening of the SELinux policy.

Pass the reference time to DispSyncThread. Since the phase offset is calculated
using timestamps relative to the reference time, we must also adjust the phase
offset by the same reference time when computing the next refresh time.
Always reset phase offset to zero when updating the reference time because the
reference time equals the first timestamp.
After beginResync() we need to keep HW vsync enabled until the model is updated.

Test: check in systrace that app/sf vsync events have correct phase
Do not use the absolute 64-bit nsecs_t timestamp directly in phase
and error calculations. Compared to the estimated vsync period, the
timestamp tend to many orders of magnitudes larger, and consequently
the integer modulo operation used to calculate phase and error can
be very sensitive to tiny fluctuation in vsync period.

Test: set kTraceDetailedInfo=true; see Phase and Error are stable in systrace

check if device is a character device, before calling

matches /dev/ashmem. So this at least eliminates making

If a single transaction has both positional and size changes, ensure we don't draw
any frames using the incorrect buffer size using the updated position. Wait for the correct
buffer size and then proceed.

Due to more complex window layouts resulting in lots of overlapping
windows, the policy around FLAG_WINDOW_IS_OBSCURED has changed to
only be set when the point at which the window was touched is
obscured. Unfortunately, this doesn't prevent tapjacking attacks that
overlay the dialog's text, making a potentially dangerous operation
seem innocuous. To avoid this on particularly sensitive dialogs,
introduce a new flag that really does tell you when your window is
being even partially overlapped.
We aren't exposing this as API since we plan on making the original
flag more robust. This is really a workaround for system dialogs
since we generally know their layout and screen position, and that
they're unlikely to be overlapped by other applications.

- Collect dumpsys to an outfile file when triggered.
- Collect dumpsys before calling Prepare on hwc module in
each draw cycle. Recollect dumpsys if Commit goes through
successfully and replace former dumpsys with this.
- Wrap around if file size reaches appx 20 MB.
- Generate output file at /data/misc/display/dumpsys.txt
- Syntax:
adb shell dumpsys SurfaceFlinger --file [--no-limit]
--file : Ouput dumpsys to file
--no-limit : Do not wrap around, keep appending
Use same command to trigger start and end of dumping.
- Output format:

SurfaceFlinger uses two event-threads to support phase-offsets
for application and SurfaceFlinger itself. Extra thread may
cause scheduling issues and wake-up latency for either
SurfaceFlinger or Application, depending on scheduling, even
when running at higher priority as these threads have low-load
and qualify for task-packing.
Use single event-thread when phase offsets are same.
Debug runtime service call behavior change when same phase-offset:
1018 (set phase offset for Application): will change both
Application and SurfaceFlinger phase offsets.
1019 (set phase offset for SurfaceFlinger): Will be a no-op.
