Mark Salyzyn 0b08d5067c lmkd: move sundry pieces to statslog.h 
Pragma once is not part of the standard, and is actually a gnu
C++ addition. Android coding standard requires the #ifndef header
wrappers. Moved things that belong in statslog.h from the lmkd files.

SideEffects: None
Test: lmkd_unit_tests

Rajeev Kumar 4aba915a62 Implement stats logging in LMKD. 
It implements logging of following atoms:
  -- LMK_STATE_CHANGED
  -- LMK_KILL_OCCURRED

We would like to gather memory metrics of the process killed by LMKD
because by gathering this info we would be able to analyze and improve
system health by potentially reducing memory footprint of the process.

This feature would be available on production builds.

To know more about this see: http://go/android-p-memory-metrics
