* LRU cache of recently-used is dead, replaced
disk storage
* ASHMEM size is read from native by the system service,
no longer requires keeping a sizeof() in sync with a
constant in Java
* Supports dumping in proto format by passing --proto
* Rotates logs on a daily basis
* Keeps a history of the most recent 3 days
Bug: 33705836
Test: Manual. Verified log rotating works by setting it up to
rotate every minute instead of day. Confirmed /data/system/graphicsstats
only has the most recent 3 entries after several minutes

If we are using HWC2, there's a change in timing
when in triple buffering with the pipelined offsets.
This changes JankTracker to recognize that and silently
erase that from the total duration

FrameInfo::duration() will remove time spent waiting
in the queue from the duration. This is desired because
that time is otherwise accounted for by the previous frame,
so we don't want to double count it.
This shows up mostly in TestSceneRunner & shadowgrid2
due to a combination of slow frame times and continous rendering.

* Dump the full histogram
* Expand the histogram to have a slow-frame section with
large 50ms buckets to raise the cap to 5s to give more
insight into system-health
* Stop excluding first-frame metrics as we want to include
those in our global tracking. Automated tests already filter
these out by doing resets before running anyway.

By setting debug.hwui.filter_test_overhead to true, hwui's
janktracker will attempt to filter out overhead caused
by the event injection that automated testing uses

If frametime > max janktracker would accidentally

Calculating duration that crosses the UI-RT
sync point will now subtract out the time spent waiting
in queue under the assumption that this time will be
accounted for in the previous frame's metrics
