Speed up access_perm, is_supervisor and is_strictly_supervisor by

adding a supervisor field to Small_conf, and using it instead of a
call to GET_C_STAT.  Remove the Conference argument to the above three
functions and update all callers.  A few stray calls to GET_C_STAT
were eliminated in the process.

+	Speed up access_perm, is_supervisor and is_strictly_supervisor by
+	adding a supervisor field to Small_conf, and using it instead of a
+	call to GET_C_STAT.  Remove the Conference argument to the above
+	three functions and update all callers.  A few stray calls to
+	GET_C_STAT were eliminated in the process.
+	* src/include/kom-types.h (Small_conf): Added a supervisor field.
+	* src/server/cache.h (cached_get_conf_supervisor): New function.
+	* src/server/simple-cache.c (cached_get_conf_supervisor): New
+	function.

+	* src/server/membership.c (access_perm_helper): New name for
+ 	former plain_ol_access_perm.  Get rid of call to GET_C_STAT by
