 /*
+ * Renames a channel in a join string: removes the channel then adds it (with
+ * its key, if set).
+ *
+ * Channels with a key are first in list, so for example:
+ *
+ *           join     = "#abc,#def,#ghi key_abc,key_def"
+ *   channel_name     = "#def"
+ *   new_channel_name = "#zzz"
+ *
+ *   => returned value: "#abc,#zzz,#ghi key_abc,key_def"
+ *
+ * If channel_name == new_channel_name (ignoring case), the function does
+ * nothing.
+ *
+ * If channel_name is not in the list, the function does nothing.
+ *
+ * If the new_channel_name is already in the list, the channel_name is just
+ * removed.
+ *
+ * Note: result must be freed after use.
