  Added a style checker for SAFE_PRINTF

Reviewed by Chris Dumez.

Forbid use of printf, fprintf, snprintf because %s is not bounds safe, and an
upcoming compiler will turn this into an error. (sprintf was already forbidden.)

Update existing format string checkers to check SAFE_PRINTF format strings.
