Extract formatters into local functions. Change the structure filtering so that
it works for taglists too.

/* structure_to_pretty_string:
* @structure: a #GstStructure
* @str: a serialized #GstStructure
*
* Converts @structure to a human-readable string representation. Basically
* the same as gst_structure_to_string(), but if the structure contains large
* buffers such as images the hex representation of those buffers will be
* shortened so that the string remains readable.
* If the serialized structure contains large buffers such as images the hex
* representation of those buffers will be shortened so that the string remains
* readable.
*
* Returns: a newly-allocated string. g_free() when no longer needed.
* Returns: the filtered string
