this is the bug change to using connection_struct* instead of cnum.

Connections[] is now a local array in server.c

I might have broken something with this change. In particular the
oplock code is suspect and some .dll files aren't being oplocked when
I expected them to be. I'll look at it after I've got some sleep.
