Subject: glib-compat: Add g_format_size

g_format_size_for_display is deprecated since glib 2.30. See glib commit
afd1e3697065c1bd23fe9a1cacf43d8744d0bc9b

g_format_size will be used in the following commit

+ * g_format_size:
+ * @size: a size in bytes
+ *
+ * Formats a size (for example the size of a file) into a human readable
+ * string.  Sizes are rounded to the nearest size prefix (kB, MB, GB)
+ * and are displayed rounded to the nearest tenth. E.g. the file size
+ * 3292528 bytes will be converted into the string "3.2 MB".
+ *
+ * The prefix units base is 1000 (i.e. 1 kB is 1000 bytes).
+ *
+ * This string should be freed with g_free() when not needed any longer.
+ *
+ * See g_format_size_full() for more options about how the size might be
+ * formatted.
+ *
+ * Returns: a newly-allocated formatted string containing a human readable
+ *     file size
+ *
+ * Since: 2.30
