Log:
Improve printing of dates and times with non-UTF-8 locales and on Windows.

* qof_time_format_from_utf8 converts an strftime format specification
  from UTF-8 to the locale encoding
* qof_format_time calls strftime repeatedly with growing allocated
  buffers until the result fits into one, or return NULL
* qof_formatted_time_to_utf8 converts the result back to UTF-8
* qof_strftime takes similar arguments to strftime, but in UTF-8
* the conversion functions on Windows are implemented in qof-win32.c to
  allow them to use windows.h, as they need wcstombs and mbstowcs
