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 9f1be12b9a lmkd: Handle cases when proc_get_name() might return NULL 
proc_get_name() can return NULL if the corresponding process has died
or open fails with ENOMEM due to memory shortages.
Ensure such cases are handled without NULL pointer access.

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.

Suren Baghdasaryan 720abce177 lmkd: choose the heaviest task when killing perceptible processes 
When killing a task at or lower than oom_score_adj PERCEPTIBLE_APP_ADJ
choose the heaviest task among the ones at that level to try minimizing
the number of required kills. Because killing a perceptible app will
affect user experience anyway, it makes sense to choose the one that
will release the most memory and therefore no more kills might be
necessary.
