mod_auth_cyrus: Add empty 'profile' table to SASL handler objects
This is for compatibility with Prosody's built-in util.sasl objects.
A SASL profile table usually includes methods supported by the backend, which
can be used by SASL mechanism handlers to perform operations (such as testing
the password). It also optionally contains a 'cb' field with channel binding
method handlers.
The Cyrus backend doesn't support channel binding, and doesn't have the same
concept of auth backend methods (it handles all that internally, and Prosody
has no insight or control over it).
Thus, we create an empty profile which informs Prosody that the SASL handler
does not support any of the auth or channel binding methods. Some features
will not work, but they didn't work anyway. This just makes it explicit.
This fixes a traceback in mod_sasl2_fast, which expected SASL handlers to
always contain a 'profile' field.

# Account based MUC joining Normally when joining a MUC groupchat, it is each individual client that joins. This means their presence in the group is tied to the session, which can be short-lived or unstable, especially in the case of mobile clients. This has a few problems. For one, for every message to the groupchat, a copy is sent to each joined client. This means that at the account level, each message would pass by once for each client that is joined, making it difficult to archive these messages in the users personal archive. A potentially better approach would be that the user account itself is the entity that joins the groupchat. Since the account is an entity that lives in the server itself, and the server tends to be online on a good connection most of the time, this may improve the experience and simplify some problems. This is one of the essential changes in the MIX architecture, which is being designed to replace MUC. `mod_minimix` is an experiment meant to determine if things can be improved without replacing the entire MUC standard. It works by pretending to each client that nothing is different and that they are joining MUCs directly, but behind the scenes, it arranges it such that only the account itself joins each groupchat. Which sessions have joined which groups are kept track of. Groupchat messages are then forked to those sessions, similar to how normal chat messages work. ## Known issues - You can never leave. - You will never see anyone leave. - Being kicked is not handled. ## Unknown issues - Probably many. ## TODO - Integrate with bookmarks - tracking outgoing presence - leaving rooms - nickname management - bookmark sync # Compatibility Briefly tested with Prosody trunk (as of this writing).
