autocleanups: Remove g_autoptr(gchar)
autocleanups: Remove g_autoptr(gchar)

- It's not sufficient, there are other bare array types
  like guint8, gdouble, etc.

- Other types like GVariant* always come as pointers, whereas
  there's a rather fundamental distinction between "gchar" and
  "gchar*" that has been signified to C programmers for 30+ years via
  the '*' character, and we're hiding that.
