2. Put debug information (mapping between blr offset and source line\column and names of local variables) into new blob field RDB$DEBUG_INFO
This is first step to implement native SQL debugger i believe
- Allow to set and drop defaults for table's fields (as it has been possible with domains).
- Stop people from setting a default value for array types.
- Close checking holes that allowed people to change from scalar types to array types and vice/versa.
- Improve some error messages.
2.- Prevent users from deleting system generators and modifying any entry in rdb$generators. VIO passes the task to DFW, the only problem being that the user gets the error when a commit is done, not before.
