libwprintf

Some rather simple implementations of wide char printf functions that were
originally written for the AmigaOS4 port of unrar.

Now converted into an easy to use static library and with added support for
floating point numbers.

The following functions are supported:
- wprintf()
- vwprintf()
- swprintf()
- vswprintf()
- fwprintf()
- vfwprintf()

Changes since the last release:

- Do not treat regular "%s" string arguments as wide char (only "%ls", "%S"
  and "%lS" are now treated as wide char). This did not cause problems with
  the unrar port as it only ever outputs wide char strings.
