/**
* Save a draft for a chat in the database.
*
* The UI should call this function if the user has prepared a message
* and exits the compose window without clicking the "send" button before.
* When the user later opens the same chat again,
* the UI can load the draft using dc_get_draft()
* allowing the user to continue editing and sending.
*
* Drafts are considered when sorting messages
* and are also returned eg. by dc_chatlist_get_summary().
*
* Each chat can have its own draft but only one draft per chat is possible.
*
* If the draft is modified, an #DC_EVENT_MSGS_CHANGED will be sent.
*
* @memberof dc_context_t
* @param context The context as created by dc_context_new().
* @param chat_id The chat ID to save the draft for.
* @param msg The message to save as a draft.
* Existing draft will be overwritten.
* NULL deletes the existing draft, if any, without sending it.
* Currently, also non-text-messages
* will delete the existing drafts.
* @return None.
