Max Horn e27b05ef35 COMMON: Rename String::printf() to String::format() 
This is a first step towards getting rid of all uses of regular printf,
fprintf, vprintf, vfprintf, puts, fputs, etc. in our codebase.

The name format() reflects the purpose of the function, and parallels
String.format() in Java, boost::format, and others.
