[TRAFODION-2044] Support SALT clause on CREATE TABLE LIKE
Formerly, several clauses (examples: SALT and STORE BY) were allowed on
CREATE TABLE LIKE, but were ignored. So, for example, one could say, "CREATE
TABLE t2 LIKE t1 SALT USING 6 PARTITIONS", but t2 would end up getting the same
salting as t1 instead.
With this change, the parser has been changed so that, except for SALT,
specifying these clauses will now result in a syntax error.
For the SALT clause, it is now fully supported with CREATE TABLE LIKE. So,
in our example above, t2 would get 6 partitions, and would be salted on the
primary key.
A new regression test, seabase/TEST040, has been added to cover this
support. The manuals have also been updated, and a few unrelated corrections in
CREATE TABLE have been made also.
This pull request also updates the expected results for regression test
compGeneral/TEST015, which has been failing for a little while. This change is
unrelated to the rest of the changes.
