new:
SurfaceFlinger: refactor frame time tracking

This change moves the frame time history tracking code out of Layer and into a
new class called FrameTracker.  It also changes the tracking to use signal
timestamps from fences when available for more accurate results.

old:
The first line currently contains the refresh period in nanosecond.
Each 128 following line contains 3 timestamps, of respectively
the app draw time, the vsync timestamp just prior the call to set and
the timestamp of the call to set.

patch:
+void FrameTracker::dump(String8& result) const {

• processFences();
• const size_t o = mOffset;
• for (size_t i = 1; i < NUM_FRAME_RECORDS; i++) {

•    const size_t index = (o+i) % NUM_FRAME_RECORDS;
  

•    result.appendFormat("%lld\t%lld\t%lld\n",
  

•        mFrameRecords[index].desiredPresentTime,
  

•        mFrameRecords[index].actualPresentTime,
  

•        mFrameRecords[index].frameReadyTime);
  

• }

void Layer::dumpStats(String8& result, char* buffer, size_t SIZE) const
{
LayerBaseClient::dumpStats(result, buffer, SIZE);

• const size_t o = mFrameLatencyOffset;
  const nsecs_t period =
  mFlinger->getHwComposer().getRefreshPeriod(HWC_DISPLAY_PRIMARY);
  result.appendFormat("%lld\n", period);
• for (size_t i=0 ; i<128 ; i++) {

•    const size_t index = (o+i) % 128;
  

•    const nsecs_t time_app   = mFrameStats[index].timestamp;
  

•    const nsecs_t time_set   = mFrameStats[index].set;
  

•    const nsecs_t time_vsync = mFrameStats[index].vsync;
  

•    result.appendFormat("%lld\t%lld\t%lld\n",
  

•            time_app,
  

•            time_vsync,
  

•            time_set);
  

• }
