JYu: deprecate the unused test from systemtest, setup a new test architecture with branchs of mandatory test, fixed test, and open test. The rasql query tests are in mandatory test folder. The PG memleak test is in fixed test folder. User can add extra test by following a similar structure.

-## This AWK-script generates some example queries, when applied on "testcases",

-## file "testcases". Each line in this file should be of the form:
-##  
-## filename @ query @ -- comment @ -- comment
-##
-## For example the line:
-##
-## mm.ql @ select 2- -1 from ImgCharA as a @ -- caution: -- introduces comments.
-##
-## should generate a test file named mm.ql with the folowing content:

-## --  caution: -- introduces comments.

-## select 2- -1 from ImgCharA as a
-##
-## The char @ is somewhat unusual for SQL and I chose it as field separator.
