           Summary: Replace all sprintf with snprintf

sprintf may write beyond the buffer passed, snprintf is the safer option.

Recent Clang compiler by default warns on the use of sprintf (deprecated) for
the c++ part of LDC. It'd be good to also remove it from D code. The fix is
usually not so hard.
