At code generation time, look at collation type to determine what kind of DVD should get generated
for character types.

                 Key: DERBY-2583
                 URL: https://issues.apache.org/jira/browse/DERBY-2583
             Project: Derby
          Issue Type: New Feature
          Components: SQL
    Affects Versions: 10.3.0.0
            Reporter: Mamta A. Satoor
         Assigned To: Mamta A. Satoor


Currently, in Derby 10.2, we generate SQLChar/SQLVarchar/SQLLongvarchar/SQLClob for various
SQL character types. All these DVDs have the default collation of UCS_BASIC. 

Starting 10.3, we should look at the collation type of the DTD before deciding what kind of
DVD gets generated for SQL character types.  If the collation type of the character type is
terriotry based collation, then we should generate CollatorSQLChar/CollatorSQLVarchar/CollatorSQLLongvarchar/CollatorSQLClob
rather than SQLChar/SQLVarchar/SQLLongvarchar/SQLClob. The CollatorSQLxxx DVDs will have the
territory based collator associated with them and hence the collation order of these DVDs
will be different than the DVDs with default collation of UCS_BASIC.
