Finally added Hans' SASL and schema patches

[Michael Ströder]

HI!

Finally I've added the schema and SASL patches contributed by Hans 
a couple of weeks ago. I did not make noteable changes so far.

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Note that some parts of the API needs additional work. Nobody 
should rely on any parts of this implementation for now.

Any complaints about "incompatible" changes made are redirected to 
/dev/null.
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Interested developers are encouraged to sync their local CVS tree, 
look at the API and comment.

Ciao, Michael.
