Suren Baghdasaryan 5263aa7800 lmkd: Do not treat RSS=0 as a sign of a process being dead 
With kernel SPLIT_RSS_COUNTING feature it is possible for a valid
process to report RSS of 0 size when reading /proc/pid/statm. This
happens because split RSS accounting aggregates per-thread counters
asynchronously and depending on the timing of the read, reported
value can be inaccurate and occasionally be 0.
lmkd currently treats processes reporting RSS of 0 as dead and
removes them from the list of processes being tracked. This might
lead to a valid process becoming unkillable.
Change lmkd to stop treating RSS of 0 as a sign of a dead process.

Bug: 160199622
Test: set ro.lmk.kill_heaviest_task=true and hack kernel to report RSS=0

Suren Baghdasaryan e68bfe9a73 lmkd: Allow lmkd to kill perceptible apps during heavy thrashing 
Occasionally a system can get into heavy file cache thrashing situation
and become unresponsive. In these situations we observe lmkd wakeups,
however it does not kill because all non-perceptible apps are already
killed and the system manages to reclaim enough memory to stay above
min watermark.
Add ro.lmk.thrashing_limit_critical property which when breached will
allow lmkd to kill perceptible apps. The property represents the
percentage of refaulted workingset pages as a fraction of overall file
cache size. By default it is disabled.
