[PATCH] Sanitize printf functions

[Kostya Serebryany]

  Let others look at this change too.
  We won't commit it before the end of our holidays (~Jan 10) anyway.

  Until we don't have tsan tests, I suggest to disable this for tsan.

we can do it as a separate commit (I'd even prefer that)

good idea. feel free to implement or to leave the TODO.
Actually this code base uses FIXME (w/o name) more often.
