	* gtk/gtkfilesystemwin32.c: Remove dead code. Reduce spurious
	differences between this file and gtkfilesystemunix.c so that it
	is easier to compare them and check if differences are
	intentional. I will later factor out the common functions and code
	snippets from these two files.

	Fix several problems with the file chooser on Windows, for
	instance prevent duplicated directory entries from appearing.

	* gtk/gtkfilesystem.c (gtk_file_paths_sort): Use
	_gtk_file_system_win32_path_compare() on Windows for casefolded
	sorting.

	* gtk/gtkfilesystemwin32.c (casefolded_hash, casefolded_equal):
	case-independent hash and equality functions. Scan the UTF-8
	strings gunichar by gunichar, and ignore special casing rules, to
	more closely match NTFS behaviour.
	(gtk_file_system_win32_init): Use casefolded_hash() and
	casefolded_equal() for the folder hash table.
	(remove_trailing_slash): Don't remove the slash of a drive or
	share root.
	(get_mime_type_for_file): Take also a WIN32_FILE_ATTRIBUTE_DATA as
	argument, and use that to recognize directories. Don't call
	g_file_test() to check for executables, just look at the file name
	extension directly.
	(gtk_file_system_win32_make_path): Check illegal chars in file
	name, like in gtkfilesystemunix.c.
	(create_file_info): Drop unused basename parameter. Call
	g_filename_display_name() directly for roots, as
	g_filename_display_basename() mishandles those.
	(gtk_file_folder_win32_get_info): Skip sanity check for now, as it
	fails for server share roots. Construct basename only in the if
	branch that uses it.
	(fill_in_names): Use casefolded_hash() and casefolded_equal() for
	the folder's stat_info hash table, too.
	(_gtk_file_system_win32_path_compare): Scan the strings gunichar
	by gunichar and ignore special casing here, too, instead of using
	g_utf8_casefold(). Match slash and backslash.
