Subject: [HACKERS] equal column and table name patch

This fixes a bug where selects fail when there is a column with the same
name as the table it's a part of.

Subject: [HACKERS] better access control error messages

This patch replaces the 'no such class or insufficient privilege' with
distinct error messages that tell you whether the table really doesn't
exist or whether access was denied.

Subject: [HACKERS] backend Makefile patch

This patch cleans up backend/Makefile a little bit, and prevents it from
relinking the backend binary when no changes have been made.

Subject: [HACKERS] abort failed transaction patch

This patch allows you to end a transaction that has failed on an error
using the 'ABORT' statement without generating another error message.
(By default you get an error unless you use 'END' to terminate the
transaction, which has already been aborted anyway.)
