WL#256: SHOW FUNCTIONS

Status: Un-Assigned

Make SHOW FUNCTIONS (or SHOW UDF) display a list of all available User-Defined Functions in one column and if loaded or not in another column.

[PeterG comment] Like worklog item #588, this is a request for a new type of SHOW. I believe that all SHOW enhancements will be redundant once we have a good implementation of INFORMATION_SCHEMA (currently worklog item #173 but needs editing). This is made obsolete by WL#2950
