REVISION SUMMARY
  Because KWin is a very old project, we use three kinds of null literals:
  0, NULL, and nullptr. Since C++11, it's recommended to use nullptr keyword.
  
  This change converts all usages of 0 and NULL literal to nullptr. Even
  though it breaks git history, we need to do it in order to have consistent
  code as well to ease code reviews (it's very tempting for some people to
  add unrelated changes to their patches, e.g. converting NULL to nullptr).

TEST PLAN
  Compiles.

REPOSITORY
  R108 KWin

BRANCH
  use-nullptr-everywhere
