[ejabberd] Intercepting authentication packets

Brief implementation plan: You can parse email within your module that
implements your custom SASL mechanism, similar to what cyrsasl_plain does;
register your SASL module, then just encode the username based on the email
to your liking and create a property list following cyrsasl_plain code. The
auth module code that you attach to your mechanism will work with "encoded"
That's the general idea, hopefully you will be able to work out details.
