Before there is a conversation, messages between users are sent
using core_message_send_instant_messages instead of
core_message_send_messages_to_conversation.
That method had an undefined $errormessage variable, ultimately
causing the problem detected on message_post_message()/message_send()
to never been returned by the external.
This just adds the same error than already existing conversations do,
but returning it as warning, for BC, JS will show it.
If blocking will have no effect (ie. you are attempting to block
the admin) the 'Block' button will not be shown and instead a
message will be shown explaining why you can not block the user.
Also, added WS new return parameter candeletemessagesforallusers in get_conversation
and send_instant_message and added API support. This will be used to check
if the user can delete all messages in the conversation.
Added new MESSAGE_CONVERSATION_TYPE_SELF type for self-conversations
and upgraded legacy self-conversations to the new type, removing
repeated members in the message_conversation_members table.
Besides, from now, a self-conversation will be created by default for
all the existing users.
All the self-conversations have been also starred and a default message
will be displayed always to explain how to use them.
The other renderables in the same namespace are still used by
deprecated web services. Once we do the final deprecation of
those web services they will be removed - see MDL-63261.
Conversation name and subname should support filters, so the data should
be passed through format_string, and advertised in the external params
as PARAM_TEXT.
Changed the settings page in the message drawer to display all message
notification processors (e.g. email, mobile, jabber) for the user to
configure based on which processors are enabled on the site.
