Suren Baghdasaryan e16047516d lmkd: Add current and max thrashing levels in LMK_MEMORY_STATS reports 
Thrashing threshold tuning requires collecting thrashing level data from
the field and correlating these levels with other indications of device
being non-responsive.
Include current and max thrashing levels in the lmkd kill reports. Max
thrashing level captures the highest level seen since the last kill report.

Suren Baghdasaryan c1171394a3 lmkd: Disable critical thrashing limit by default 
Critical thrashing limit determines the balance between how much
thrashing should be tolerated before killing a perceptible app.
This threshold might differ between devices, therefore we disable
critical thrashing limit by default allowing each device to set it
individually. This is done to prevent excessive kills of perceptible
apps.

Suren Baghdasaryan 57f12d13ce lmkd: Add ro.lmk.filecache_min_kb property for min filecache watermark 
We see many cases when device keeps thrashing despite lmkd kills. This
happens because killed processes do not free enough filecache to fit
the current workingset completely.
To prevent such cases, introduce ro.lmk.filecache_min_kb property to
specify min filecache size in KB that should be reached after thrashing
is detected. Lmkd will keep killing background processes until this
filecache size limit is satisfied.
