Finally I've merged this new feature in master.

These are the changes I did after some comments:

- Added a new function, grl_plugin_registry_get_metadata_keys()
function, which returns a list with all registered keys in registry.

- grl_media_serialize() is a wrapper over
grl_media_serialize_extended(), performing a basic serialization.

- grl_media_serialize_extended() now uses a GrlMediaSerializeType to
specify how to perform the serialization.

Right now there are 3 approaches:

- GRL_MEDIA_SERIALIZE_BASIC: it is the old way
grl_media_serialize(media, FALSE). It uses only "id" and "source" to
perform serialization, getting rid of remaining keys.

- GRL_MEDIA_SERIALIZE_FULL: it is the old way grl_media_serialize(media,
TRUE). It uses all available keys to perform serialization.

- GRL_MEDIA_SERIALIZE_PARTIAL: it uses "id", "source", and a list of
user-specified keys to perform serialization. Remaining keys are
ignored.

When using GRL_MEDIA_SERIALIZE_PARTIAL, a third parameter is required, a
GList with the keys to take in account. E.g.:

   GList *keylist = grl_metadata_key_list_new (GRL_METADATA_KEY_TITLE,
GRL_METADATA_KEY_URL, NULL);
   gchar *serial = grl_media_serialize (media,
GRL_MEDIA_SERIALIZE_PARTIAL, keylist);
   g_list_free (keylist);
