Suren Baghdasaryan 858e8c6373 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.

Ioannis Ilkos 4884890305 Log killed process swap size 
We already log the rss size for the process. Given lmkd strategies also consider low swap, it will be beneficial to record the swap size too.

Chris Morin 74b4df95b4 Replace mentions of "oom_adj" with "oom_score_adj" 
Some log messages mention "oom_adj" instead of "oom_score_adj" when
referring to oom_score_adj. This is confusing because "oom_adj" is a
separate value which was supplanted by oom_score_adj, but can still be
used.
