isql embedded hangs when trying to quit after an error (thanks Vlad for solution).

Add the missing ACL_end because walk_acl() doesn't detect the end of the stream and reads trash instead, producing the strange message (unrecognized ACL) instead of the denied access right.

- I was caught by a null pointer due to an error reported by the engine in embedded mode. I prefer the code generated by gpre to be redundant for now.
- When starting multiple txns, the code was printing the next, not the current in the loop.

Gpre was generating code to connect isql to the build db (yachts) instead of the runtime db.

The new API requires checking for null pointer before, not after the call. Maybe there are other places that need adjustment.
