Convert message to UTF-8. Technically this breaks API, but the actual use

	* glib/gwin32.c (g_win32_error_message): Convert message to
	UTF-8. Technically this breaks API, but the actual use cases in
	gdk/win32 have assumed it is UTF-8 anyway. Fix
	documentation. (#152618, Kazuki Iwamoto)

	* glib/gwin32.h: Don't define ftruncate as a macro. Was never a
	good idea, and it clashes with newest mingw headers, which have a
	ftruncate implementation as an inline function. Thanks to Dominik R.

	* glib/gwin32.c (g_win32_ftruncate): Simplify implementation, just
	call _chsize() in the C library.
