Enhancements to the alternate (WIP) format string checking:

- Add ConversionSpecifier::consumesDataArgument() as a helper method
  to determine if a conversion specifier requires a matching argument.
- Add support for glibc-specific '%m' conversion
- Add an extra callback to HandleNull() for locations within the
  format specifier that have a null character
