Fix some issues with fawzi's patch.
- It now actually compiles:
- import stdc.stdio for string formatting functions)
- remove extra '{'
- Use snprintf() instead of sprintf().
- Use return value from snprintf instead of strlen().
- Don't print the filename in Exception.writeOut() if it has zero length and
the line number is 0
(It would previously only skip these if the filename was null, but not if it
was a different empty string)
- Ignore empty filename + line number 0 in FrameInfo.writeOut() as well.
