[PATCH] Sanitize printf functions

[Yury Gribov]

  Updates based on feedback from Evgeny&Alex.

  What's missing:
  * I haven't added the @LINE directives; currently ASan reports
      #0 0x431593 in printf_common
      #1 0x431a94 in __interceptor_vprintf
      #2 0x42b2fd in printf
      #3 0x47a897 in main
  which probably is not what we want but I don't think that we should fix it in this patch.

  Regarding glibc tests: I've ran them and verified that ASan does not cause segfaults or test failures (it does print couple of warnings on invalid format strings). Is this what you guys wanted?
