* 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

Bug: 30440166
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

Bug: 27922347
* 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.

Fixes: 27795291
Track the 10 slowest frames over the last 24 hours
to try and give approximate insight into total system health.

Add CLOCK_MONOTONIC to signal
when the stat collection started
to allow for tracking stats
over time

More S's for More Speed
Split JankTracker's backing data from the
class to allow for data relocation to/from ashmem regions
Pack the jank tracking data to fit in 256 bytes
